Preheat oven to 350º. Oil your muffin/pan slots with oil using a brush and set aside.

Beat the eggs with the shredded cheese in a medium mixing bowl and set aside.

Using a non-stick skillet, brown the bacon. Add the sausage crumbled, stirring and cooking until it is no longer pink. Add onion and saute just until onion begins to cook/wilt. Remove from heat and cool 1-2 minutes.

Add the meat mixture to the egg mixture and beat together well with a spoon. Using a ¼c. measuring cup, scoop up ¼ c. of the mixture into each of 8 slots.

Pop into preheated 350º oven for about 18-20 minutes until just set and barely beginning to brown on tops. Remove from pans/slot with a knife tip and serve at once.
