Vegetarian “Sausage” and Egg Breakfast Casserole – Gluten Free

One of my favorite breakfasts is my aunt’s sausage, egg and hash brown casserole.  I wanted to make it vegetarian, but have had a tough time finding gluten free vegetarian “meat” patties.

However, a clever friend of mine happened along “The Original Sunshine Burger” at Whole Foods. Not only was it marked “gluten free,” but also all natural, vegan and soy free.

Made with sunflower seeds, they are pre-baked, browned and packed full of protein.

The key with this dish, as with any of my hash brown casseroles, is to pre-bake your hash brown crust to get it crispy and brown. If you skip this step, the consistency of the hash browns is too similar to that of the veggie patties and doesn’t provide enough texture variety.

This is a great make-ahead dish and warms up great for serving the next day.
