Ingredients

• 8 eggs*
• 4 thick slices bread cubed
• ½ cup cheddar cheese shredded
• 1 lb ground sausage*

• 6 roasted tomatoes
• 2 medium sweet potatoes cubed

Instructions

• Brown the sausage in a frying pan, moving around occasionally. Chop up the potatoes and bread, and shred the cheese while browning.
• Cover the bottom of your casserole dish with sweet potato cubes, ensuring you leave no large gaps.
• Evenly spread the browned sausage over top of the sweet potatoes.
• Place the roasted tomatoes on top of the sausage meat, and crush with the back of a wooden spoon.
• Depending on the consistency of your avocado, either add cubes or dollops of the avocado over the tomato layer. Cover the avocado completely with bread cubes.
• Combine the eggs and cheese. Pour over top of the whole casserole. Cover with aluminum foil and refrigerate overnight.
• The next morning, bake at 350F for 1 ½ hours, uncovered, until the eggs are fully set.

Notes

*Editor's Notes: I would personally use a dozen eggs, but only 3-4 of the yolks to make this casserole, and would select a good quality chicken sausage.
