Preheat your oven to 350F. Grease a 9 x 13-inch baking dish and set it aside.

Steam or microwave the cauliflower until it’s lightly tender. In a non-stick pan, heat some oil over medium heat. Add the onions, peppers, and crumbled sausage to the pan. Cook for about 3-4 minutes until the sausage is nicely browned.

Transfer the cauliflower, veggies, and sausage into the baking dish. In a separate bowl, whisk together the eggs, egg whites, cottage cheese, shredded cheese, salt, and pepper. Pour this mixture over the ingredients in the baking dish.

Bake for 35-40 minutes, or until the center is set and cooked through.

Remove from the oven and serve hot, or let it cool completely before serving.
