Here is an idea:
It's called Fish Goulash and is probably Hungarian, courtesy of this book:
I changed the recipe slightly, as usual.
You will need frozen fish fillets, (4 to serve 4) I used Alaska pollock
Fish or vegetable bouillon cubes
onions, green bell peppers, carrots, tomatoes (save some for serving)
tomato puree, olive oil, salt, chili sauce
Heat olive oil in a large frying pan, add sliced green pepper, onion and carrot, stir-fry for some time. Add frozen fish fillets, pour enough water to cover, add 1-2 bouillon cubes, tomato puree and some tomatoes, salt and chili sauce to taste. Cook until fish is ready, for about 15 min. Serve over rice with sliced avocado, some fresh sliced tomatoes and sour creme. Simple and delicious!
