Preheat oven to 400°F (200°C fan). Add tomatoes, chopped peppers, onion, garlic, and feta to a large baking dish.
Season with spices, salt, and pepper. Drizzle with olive oil and roast for 40–50 minutes until beautifully golden.
Transfer everything, including the roasting juices, to a blender. Add cottage cheese, rinsed white beans, fresh basil, and chicken broth. Start with less broth and adjust until creamy. Blend in two batches if your blender isn’t large enough.
Blend until silky smooth. Gently reheat if needed, then top with fresh basil and chili flakes.
