A nourishing frittata with seven eggs, fresh spinach, creamy feta and sweet cherry tomatoes. This Mediterranean classic starts your day heartily with protein and healthy fats, and is equally delicious cold for lunch.
The smell of olive oil and oregano fills the kitchen before the frittata even goes into the oven. In the skillet: wilted spinach, dark green and glistening, half-submerged in a golden egg mixture. Between them crumbled feta softly melting, and halved cherry tomatoes releasing their juices. The edges set slowly on the stove, then the pan goes into the oven — ten minutes later out comes a golden disc brimming with flavor. Let it rest, cut into wedges. Eat warm with bread, or cold the next day straight from the fridge.

Nutritional Synergies
This recipe combines ingredients that enhance each other:
Cherry Tomatoes 
Olive Oil Olive oil increases lycopene absorption from cherry tomatoes 2-3x
Technical: Cherry tomatoes contain 2573μg lycopene per 100g. Lycopene is fat-soluble and only 2-3% absorbed without fat. Olive oil's oleic acid forms mixed micelles increasing lycopene absorption 2-3x. Cherry tomatoes contain relatively more skin (where lycopene concentrates) than regular tomatoes due to their small size.
What does this mean for you? Halve cherry tomatoes and roast in olive oil, or serve in salad with olive oil dressing. Their higher skin-to-flesh ratio means more concentrated lycopene.

Eggs 
Spinach Increases vitamin E absorption by factor 4-7
Technical: Spinach contains vitamin E (2mg/100g), lutein and beta-carotene — all fat-soluble. A study showed that adding an egg (with 5g fat) to a raw vegetable salad increased vitamin E absorption by a factor of 4-7. The egg yolk creates a lipid emulsion serving as transport for these fat-soluble nutrients.
What does this mean for you? Always add an egg to your spinach salad or cook spinach with an egg. Without the egg fat you absorb up to 7x less vitamin E from the spinach.
General Wellness
Feta Cheese Olive Oil Olive oil improves calcium absorption from feta
Technical: Feta contains 493mg calcium per 100g. Fat-soluble vitamins D and K2 are needed for calcium absorption. Olive oil contains mono-unsaturated fats that improve absorption of these vitamins and minerals. Olive oil also contains oleuropein involved in bone metabolism.
What does this mean for you? Always drizzle feta with olive oil — the Mediterranean tradition of feta with olive oil is scientifically smart.

Oregano Olive Oil Fat makes carvacol and thymol absorbable
Lambert JD et al. (2004) in Molecular Nutrition & Food Research showed that dietary fats enhance absorption of phenolic compounds from herbs.
Technical: Oregano contains carvacrol (60-74%) and thymol (1-5%) — potent phenolic compounds with broad bioactivity, traditionally valued in food preservation. These compounds are fat-soluble and poorly absorbed without fat. Olive oil dissolves them and significantly increases their bioavailability. This explains why oregano oil always comes in a carrier oil.
What does this mean for you? Cook oregano in olive oil or make oregano-olive oil dressing. The bioactive compounds in oregano are fat-soluble — without oil you barely absorb them.

Spinach Olive Oil Makes fat-soluble vitamins and antioxidants available
Technical: Spinach contains 483μg vitamin K (403% RDI), 5626μg beta-carotene, 2mg vitamin E and 12.2mg lutein — all fat-soluble. Without fat only 5-10% is absorbed. Olive oil's monounsaturated fats (73% oleic acid) form micelles that increase absorption 2-5x.
What does this mean for you? Always eat spinach with olive oil or another fat source. Without fat you waste most of spinach's impressive vitamin profile. A drizzle of olive oil is essential for proper absorption.

Spinach 
Black Pepper Increases beta-carotene absorption from vegetables
Technical: Spinach contains 5626μg beta-carotene per 100g. Piperine from black pepper (5-9% by weight) inhibits glucuronidation in the gut, keeping beta-carotene in its active form longer. Piperine also increases intestinal epithelium permeability via vanilloid receptor activation.
What does this mean for you? Grind fresh black pepper over spinach. Piperine slows beta-carotene breakdown in your gut so you absorb more. Combine with olive oil for the maximum triple effect.

Sea Salt Olive Oil Minerals + polyphenols for cellular balance
Technical: Sea salt's sodium is essential for the sodium-potassium pump (Na+/K+-ATPase) that regulates every body cell. Olive oil's oleuropein and hydroxytyrosol provide antioxidant protection for cell membranes. The combination supports cell integrity: sea salt regulates ion balance, olive oil protects the membrane. In Mediterranean cuisine, coarse sea salt + olive oil is the most basic flavor profile.
What does this mean for you? Freshly ground sea salt with extra virgin olive oil is the simplest and most nutritious finishing of any dish. The combination provides the basic needs of your cells: minerals for function, polyphenols for protection.

Black Pepper Olive Oil Fat increases piperine absorption and enhances polyphenols
Technical: Piperine is fat-soluble and absorbed 2-3x better with dietary fat. Olive oil's oleocanthal and piperine both modulate COX signal transduction through different mechanisms, providing additive bioactive effect.
What does this mean for you? Grind fresh pepper over salads with olive oil dressing. The combination enhances both pepper absorption and bioactive action.
