It's summer, it's hot, and no one wants to be in the kitchen, but the juicy burgers on the grill are just calling for french fries on the side. Luckily, you don't need to heat up the oven (or fryer) because frozen french fries can be made on the grill. This ingenious cooking method ensures that the spuds still turn out incredibly crispyand makes it easy to smother the fries in cheese, bacon, and chives. It's important to use frozen fries for this cooking technique because freshly cut potatoes will not achieve the crispiness you're looking for. If you need to make a larger batch of fries, create more aluminum boats instead of overcrowding them in one pouch; the fries will steam instead of crisping up, and no one wants soggy french fries.
