Preheat oven to 350 degrees.

Cook bacon - I like to bake mine ahead of time and freeze it. To bake bacon, cook it at 350 degrees for 15-20 minutes, turning half way through the cooking time and watching closely at the end to make sure it doesn't burn.

Combine eggs, milk, cheese, spinach, salt and pepper. Whisk well with a fork.

Warp bacon around each cup of a muffin pan. By the way, I love my stone muffin tin. I use it all the time and rarely have food stick to it.

Divide egg mixture evenly into muffin pan.

Bake for 18-22 minutes, or until eggs are cooked.
