Preheat the oven to 400°F.
Place the small broccoli florets, onion, garlic and feta in an oven-safe dish. Drizzle with olive oil and add oregano, 1 tsp chili flakes, salt and pepper.
Roast for 35–40 minutes, checking as cooking time varies by oven.
Blend everything from the roasting dish with the cottage cheese, bone broth, spinach, lemon zest and juice, and beans until smooth. Add water if too thick.
Warm the soup, spoon into bowls and garnish with dill, chili flakes and shredded Manchego or Parmesan.
