Preheat oven to 375°F. Rub a baking dish or muffin tins with a little oil.
Heat oil in a large non-stick or ceramic skillet over medium heat. Add onion, bell pepper, and carrots, and cook until slightly tender, about 7 minutes. Add mushrooms, and cook until they release their juices, about 5 minutes. Season with oregano, garlic powder, red pepper flakes, and cayenne pepper. Stir in spinach, and cook until all liquid from spinach has been absorbed. Remove from heat.
In a large mixing bowl, stir together cottage cheese, eggs, and cheese. Once combined, stir in vegetable mixture.
Pour mixture into prepared muffin tin or baking dish, and bake in preheated oven for 24-28 minutes until eggs are set. Remove from oven and let cool about 5 minutes before serving.
Promptly refrigerate leftovers. Keeps refrigerated for 5 days and frozen for 1 month.
*Makes 16 regular sized muffins
