Ready, Set, Cook! Reynolds Wrap Contest Entry. I love this recipe because it highlights all of the ingredients present. It also uses a summer seasonal ingredient in a very unique way. When peaches are grilled they bring a delicious sweetness which pairs wonderfully with the Tilapia. The rosemary adds a nice punch of earthiness and spiciness to the dish without being too overwhelming. It is a perfect compliment to the fish and the peaches.
