Basic Cheese Omelet
2 tablespoons milk
Salt and pepper, to taste
1⁄4 teaspoon (or to taste) chili powder
1 tablespoon butter
1⁄4 cup grated cheese
Lightly beat the eggs with the milk. Stir in the salt, pepper, and chili powder. Melt the butter in a frying pan over low heat. Swirl the butter around to coat the pan entirely.
Pour the egg mixture into the pan. Cook over low heat. After the omelet has been cooking for a few minutes, sprinkle the grated cheese over half of the omelet. Tilt the pan occasionally or lift the edges of the omelet with a spatula so that the uncooked egg runs underneath.
When the omelet is cooked evenly throughout, loosen the edges of the omelet with a spatula. Carefully slide the spatula underneath the omelet and fold it in half. Slide the omelet onto a plate.
