Preheat your oven to 375 degrees.

Spray your dish with cooking spray. I used a 1.25 qt dish, you can also use a 9x9 or a pie plate.

I cooked my bacon, let it drain on paper towels then crumbled it.

Then throw the onions into the bacon grease to saute them till soft and got them out with a slotted spoon.

Put your onion, cheese and crumbled bacon into the bottom of the casserole dish.

Mix together in a separate bowl the milk, eggs, and Bisquick.

Pour over you goodies in the casserole dish.

Bake for 30-40 minutes till eggs are cooked through.
