Add vegetables or meats to the pan. Sauté for 5 minutes or until softened. If using pre-cooked ingredients, heat them until warmed through.

In a mixing bowl, beat eggs, milk or cream, salt, and pepper until well combined. The mixture should be slightly frothy for a fluffy texture.

Gently pour the egg mixture over the sautéed fillings in the pan. Stir lightly to distribute the fillings evenly. Cook on the stovetop over medium heat for about 5 minutes or until the edges begin to set.

Transfer the pan to the preheated oven and bake for 10 to 12 minutes, or until the center is firm and the top is golden. Let the frittata rest for a few minutes before slicing and serving.
