Preheat the oven to 350ºF and grease a 12-cup muffin tin.

Divide sausage into 12 parts. Press 1/12 of the sausage into each cup's bottom and sides.

Break the eggs into a large bowl and beat, adding the desired chopped vegetables. Distribute evenly in the 12 muffin cups.

Sprinkle 1 tablespoon of cheese on top of each muffin.

Bake for 20 minutes or until the eggs are cooked.
