Preheat your oven to 375°F (190°C). Lightly grease a 9x13 inch baking dish with cooking spray or a little olive oil. This ensures your High Protein Cottage Cheese Turkey Sausage Casserole won't stick and makes for easy serving.

Heat 1 tbsp olive oil in a large skillet over medium heat. Add 1 medium yellow onion, diced, and 1 large red bell pepper, diced. Sauté for 5-7 minutes until softened. Add 3 cloves garlic, minced, and cook for another minute until fragrant.

Add 1 lb lean ground turkey sausage to the skillet with the vegetables. Break it apart and cook until browned, about 8-10 minutes. Drain any excess fat. Stir in 5 oz fresh spinach until just wilted, then remove from heat.

In a large bowl, combine 24 oz low-fat cottage cheese and 4 large eggs. Whisk well until thoroughly combined. Stir in 1 tsp dried oregano, 1/2 tsp dried thyme, 1 tsp salt, 1/2 tsp black pepper, and 1/4 tsp red pepper flakes (if using).
