Just as you would meal prep lunches for the week, making a large breakfast casserole ahead of time will feel like a lifesaver on hectic Monday mornings. If you're running late for work, you'll have a nutritious grab and go option, and you can simply pop it in the microwave for your kids to eat before school. The following breakfast casserole recipes taste great, are pretty to look at, and will leave you feeling full until lunch time.
