In a small bowl, lightly mix eggs just until yolk and albumin are combined.
Mix in milk, veggies, herbs, and half of cheese. Good melting cheeses include Fontina, gruyere, cheddar... but by all means use your favorite...brie, feta, goat.
Brush inside of very hot skillet with olive oil, and pour in egg mixture. In 2 to 3 minutes, when egg is pulling away from the sides of the skillet, top with remaining cheese and move Skillet to the oven. Bake for approximately 5 to 8 minutes, and remove from oven when Center is still loose. The skill it is so very very hot, the frittata will continue cooking when removed from the oven. If you baked the frittata until the egg is completely set, your frittata will be overcooked when you slice into it.
