Spray a muffin tin with cooking spray and preheat oven to 350 degrees.

Cut 12 circles out of bread, making sure they are the same size as the bottom of the muffin tin.

Place each bread circle into a muffin cup.

Cook sausage links according to package directions and chop into small pieces.

In a large bowl beat eggs and add in sausage, salt and pepper.

Fill each muffin cup ¾ full with the egg mixture.

Sprinkle cheese on top of egg cups.

Bake at 350 degrees for 15 minutes if you are cooking in a toaster oven or for 20 minutes if cooking in a normal oven. When muffins are done, they will be firm and a fork inserted in the center will come out dry.
