Opinions are divided about whether you should marinate meat before grilling of not. In any case, it is a fact: the better the quality of meat, the more dispensable the oil and marinades. It�s best just to try it yourself. But remember: you should pat marinated meat dry before grilling, otherwise the marinade, which contains oil, will drip into the fire.
Here are a few suggestions of how you can marinate your meat:
