Name: Vegetable Omelets
Ingredients: 2 tablespoons cooked cauliflower; 2 tablespoons cooked French beans; 2 tablespoons cooked spinach; 1 tablespoon butter; pepper to taste; coarse sea salt to taste; eggs (as needed for omelet)

Why it works: Beans and spinach match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 365 recipes. Both carry 2-isobutyl-3-methoxypyrazine, which smells green bell pepper, earthy. The science ↓
