Preheat your oven to 350 degrees Fahrenheit.

In a medium skillet, heat the olive oil over medium heat. Add the turkey sausage and cook until it’s completely browned, about 10 minutes. Transfer the cooked sausage to another dish.

In the same skillet, add the diced onion, minced garlic, and bell peppers. Sauté over medium heat for 4-5 minutes until softened. Remove from heat.

While the sausage and veggies are cooling, combine the eggs, cottage cheese, shredded cheddar, salt, and black pepper in a medium bowl. Blend until smooth.

Stir the cooked turkey sausage and sautéed vegetables into the egg mixture until fully combined.

Pour the mixture into a large nonstick or lightly greased 9x13" casserole dish. Bake for about 40-50 minutes, or until the center is firm. If the top browns too much, cover with aluminum foil for the last 10 minutes. Allow to cool for 10 minutes before slicing.
