An Italian breakfast casserole is the perfect way to start ANY day. It combines some breakfast favorites into an easy to make casserole that will feed you all week long! Or, at least feed your family for a morning. And, they sure won’t complain. In fact, you may want to double it to be sure you have enough for everyone because you’re all sure to want seconds!

This recipe uses Organic MuscleEgg egg whites, but our Original plain egg whites will work just as well. Add some sausage mushrooms and what we feel is the secret ingredient – arugula – and you’ve got a breakfast worth making at least once a month! With all the flavors you’d expect, you may want this Italian breakfast casserole even more often than that!
