Crack the eggs into a medium mixing bowl. Add your dairy of choice, several dashes of hot sauce, plus the salt and pepper. Whisk just until the egg yolks and whites are blended.
Stir in half of the cheese (we’re reserving the other half for topping the frittata before baking). Transfer the lightly cooled veggies into the bowl, and stir to combine.
Pour the mixture into the prepared pan. Evenly disperse the remaining cheese on top.
Bake for 25 to 35 minutes (keep an eye on it), until the eggs are puffed and appear cooked, and the center of the frittata just barely jiggles when you give it a gentle shimmy. For good measure, insert a fork about ¼-inch into the center of the eggs and make sure the fork comes out clean
Place the frittata on a cooling rack until you’re ready to serve. Slice with a sharp knife, and serve. Leftovers will keep well for about four days in the refrigerator. Enjoy leftovers chilled, at room temperature, or gently reheat in the microwave or oven.
