Spray or oil the aluminum foil and place your meats, fish, kabobs, etc. on the foil and then put the foil directly on the grill surface.
A little bit of salt sprinkled on the foil ``depending on what you're cooking of course'' will stop foods sticking to the foil. Works for chicken breast anyway!
If you must place on foil, use non stick side of foil or treat surface with a little olive oil or non stick spray hope this helps and be careful not to place over extreme heat…
You can use a cooking oil or non-stick spray, but only on a cold grill. Since spray cooking oils are aerosol (with contents under pressure), they should not be exposed to direct, high-heat as the spray can could explode or burst into flames.
Oil the meat
Oiling your meat is the easiest way to keep it from sticking to the grates. Before oiling, make sure the meat is dry. Use clean paper towels to remove any excess moisture from the meat before oiling. Then, lightly coat the meat with oil before putting it on the grill.
Once the pan is preheated, add oil or cold butter and allow the fat to heat up before adding food. “This 'hot pan, cold fat' method prevents food from sticking,” Staley says.
First, put a light coating of olive oil and seasoning directly on the chicken to help prevent sticking. Second, keep the grill temperature around 425-450F. If the temperature is too high the chicken will stick! You want to grill the chicken breasts for about 4.5 min a side.
Oiling your grill grate helps prevent food from sticking when cooking. To do this, dip a wadded paper towel in a little oil and, using tongs, wipe the oil evenly over the grate. Be careful not to use too much oil, because that's a sure fire way to start a good flare-up—a little goes a long way here.
So aluminium is in principle ideally suited for grilling: it offers protection against high temperatures, the food doesn't burn so quickly and doesn't stick to the grid. Food that's wrapped in aluminium foil, e.g. fish and vegetables, stays tender and succulent, and has a more intense flavour.
lubricated -- a quick coat of cooking oil on a hot grill grate will season it and help food release easily. hot -- the grill needs to be hot before you add food to it; the hot grates sear the food and help it release better.

Be sure to lightly spray or oil your foil to prevent sticking. You can also use non-stick foil. Prep your chicken and ingredients: Coat your chicken and accompanying ingredients in your preferred seasonings and flavorings. If you're using a marinade, let it soak into your chicken for at least an hour before baking.
Right before grilling, just rub those hot grates with the cut end of a potato. The starch in the potato creates a non-stick surface.
Once the grill is clean, apply a vegetable or olive oil to the grates to prevent the steak from sticking to the grill. You don't need to preheat the grill before applying the coating of oil. The oil will automatically create a barrier, which will keep steaks from sticking.
Cooking Temperature: Achieving the right cooking temperature is essential. Using a cold grill or not preheating it properly will cause food to stick. If it's too hot, food may burn and stick.
Not Enough Fat
If your food sticks, there is a chance that you simply didn't use enough oil. That said, you don't need to get carried away with oiling your foods and cooking vessels — a thin layer of fat, combined with heat and time, should do the trick beautifully.
With a grilling fork, make drainage holes in the foil. Ensure that the dull, non-stick side is facing up. Place the burgers on the foil. To retain the juiciness of your burgers, it's best to flip them only once during cooking, about 5 minutes into the process.
If you're grilling, that means oiling the grate. I use a pair of tongs to lightly dip a wadded paper towel into some high-heat cooking oil, then rub the paper towel over the grate to give it a light coating. If the grate is nice and hot beforehand, the fat will heat up immediately.
