Preheat the oven to 375°F (190°C) and lightly grease a small baking dish or two oven-safe ramekins.
In a mixing bowl, combine the cottage cheese, Greek yogurt, ¼ cup mozzarella, Parmesan, Italian seasoning, garlic powder, onion powder, salt, and black pepper until well mixed.
Spread the mixture evenly into the prepared baking dish.
Spoon the pizza sauce over the top, then sprinkle with the remaining mozzarella.
Add the mushrooms, bell pepper, red onion, cherry tomatoes, and black olives.
Bake for 20-25 minutes, or until the cheese is melted and bubbly. Broil for 2-3 minutes for a golden, lightly browned top if desired.
Let the pizza bowl rest for a few minutes before garnishing with fresh basil and red pepper flakes. Serve warm.
