Plain Chicken: Maple Sausage and Waffle Casserole. Switch out the eggo waffles with paleo waffles, use turkey sausage, pure maple syrup, almond milk instead of regular, and hold the cheese-- it becomes totally paleo friendly!
Bubble Up Breakfast Casserole.I served this at a baby shower/brunch and it was a big hit! copycat recipe off my Great Grandma's Breakfast Casserole! good job on the substitutes, but can use a loaf of bread instead of biscuits if needed :)
Cauliflower Mac and Cheese: Hold the mac, but not the cheese. Save on a few carbs with this creative cauliflower mac and cheese recipe from Vegetarian Times. Can make a Nutritional Yeast sauce instead of cheese!
Cheesy Potato Breakfast Casserole (w/eggs sausage). Option: Instead of frozen potatoes, use 4 med potatoes and bake them in the microwave and then chopped them up. Try breakfast sausage or chorizo instead of Italian.
