In a large skillet over medium-high heat, cook and crumble the sausage until no longer pink.
In a separate skillet, melt the butter and scramble the eggs. Season with a little salt and pepper. Add the cooked sausage to the scrambled eggs, stir to combine. Cover and keep warm.
Roll the thawed waffles flat. Drape them over a loaf pan. Bake at 425 degrees until crisp, about 5 minutes. Fill the waffle tacos with the egg and sausage mixture. Top with shredded cheese and serve with your favorite salsa or maple syrup.
