I wanted to come up with a filling breakfast for my boys to get them through the morning. Going off a breakfast casserole recipe, I modified it to make these hearty, energy filled muffins. I am going to work on a healthier version next go around, using ground chicken. *These freeze well. *Could be baked as a casserole in a 9 x 9 pan. 350 F for approx 1 hour. *Use glass, ceramic or best choice, stoneware. Metal pans turn the bottoms too dark.
