Preheat oven to 400 degrees Fahrenheit and spray a small baking dish (either a 9-inch ceramic pie plate or an 8x8-inch glass baking dish) with cooking spray. Set aside.

Melt ½ cup of butter in a large saute pan over medium-high heat. Once butter is melted, add pretzel bread cubes. Toss in butter and toast until all sides are golden-brown. Transfer from saute pan to a large mixing bowl.

Place the same large saute pan over medium heat and melt additional tablespoon of butter. Add onions and saute for a few minutes, until beginning to get fragrant and turn translucent. Add apples, cinnamon, cayenne and nutmeg. Saute for an additional 5-10 minutes, until apples and onions are cooked through.

Add apple mixture to pretzel cubes in large mixing bowl. Add sausage, eggs, almond milk and 2 cups of grated cheddar cheese. Stir to combine.

Pour into prepared baking dish and sprinkle remaining ½ cup of grated cheddar cheese over top. Bake in 400-degree oven for 30 minutes, or until top is golden brown and bubbly.

Cool slightly and then serve.
