Preheat oven to 375 degrees Fahrenheit and grease a 9x9 inch glass baking dish.
In a large mixing bowl, whisk the eggs until the yolks and whites are fully incorporated.
Add the cottage cheese, garlic powder, onion powder, oregano, salt, and pepper to the eggs and stir until combined.
Fold in the spinach, broccoli, and red bell pepper into the cottage cheese mixture.
Pour the mixture into the prepared baking dish and spread into an even layer.
Sprinkle the shredded cheddar and grated Parmesan cheese evenly over the top.
Bake for 40 to 45 minutes until the edges are golden brown and the center is set.
Allow the dish to rest for 10 minutes before slicing to ensure the structure is firm.
