1. Boil the head and tail of the fish for half an hour. 2. Take out the fish in the broth put chopped potatoes, onion, grated carrot, bell pepper, garlic and black pepper. Spices to taste, and pieces of fish. 3. Separately in a small amount of water or broth to dissolve the cheese. Add to soup and cook for another 20 minutes. In principle, it is possible to put cheese directly in the soup, but it dissolves longer. 4. At the end, add the greens. The soup looks easy enough. Ie not as satisfying as the soup, for example. I sometimes eat from 2-3 plates! :)
