I don't know if the red pepper you mentioned is fresh or dry. If it is fresh, stir-fry the green pepper first, and then put the red pepper. Because the green pepper itself has a grassy smell, you can remove this smell by frying it first; If it is dry red pepper, put red pepper first and then green pepper, which will be more fragrant. When frying, put a little oil in the pan, then saute pepper, onion and garlic, add pepper, add vinegar, salt and soy sauce, stir fry a little, and you can get out of the pan. Remember not to fry for too long, because there is still residual heat after frying, and the pepper will cook itself. Eating like this will make the taste and taste worse.
