Crockpot Breakfast Casserole

Cook sausage, bacon, or ham if needed and set aside.

Spray the inside of the crockpot or the Ninja Foodi pot with olive oil cooking spray.

Whisk together the eggs, milk, mustard, salt, and pepper until combined well. Set aside.

Add hash browns to the bottom of the crockpot or the Ninja Foodi pot.

On top of the hash browns, layer half the meat, peppers, onion, and 1 cup of cheese.

Repeat the layers.

Pour the egg mixture over the ingredients.

Cover and cook on low for 7-8 hours or 3-4 hours on high.

If using the Ninja Foodi - use the glass lid or the pressure cooker lid with the nozzle set to 'vent' and cook for 8 hours on low or 4 hours on high.

Serve immediately.

Leftovers can be stored for up to 4 days.
