Fish can be prepared and cooked (or even baked) in several ways. There is no exact answer to this question because it will depend on what kind of dish you are planning to make. However, if you would like to make grilled fish, here are the ingredients that you would need: 1 teaspoon of minced garlic (about 3 cloves), ½ cup of extra virgin olive oil, ¼ cup of lemon juice, 1 tablespoon of balsamic vinegar (but you can use any vinegar of your choice), pinch of hot red pepper flakes (entirely optional if you want it to have a little spice), ½ teaspoon of ground cumin, pepper, and fish steaks.
First, combine all the ingredients and then marinate the fish for at least 30 minutes. Brush your grill with some oil to prevent the fish from sticking and then preheat it for about 10 minutes. Once it is hot enough, cook the fish for 4 to 5 minutes on each side or until it becomes opaque. Remove immediately and serve.
