Yummy! The potatoes get much and brown around the edges while the centers stay soft and moist. The carrots not only taste delicious but they add such a nice touch of color. There's just enough onion to add some savory flavor along with the garlic and rosemary. We grill over medium low heat and it takes about 20 minutes to cook completely. Turn the packages over every few minutes to ensure even cooking. I use a piece of heavy duty aluminum foil, about 18-20 inches in length for each serving. Just fold over the edges a few times and crimp them closed. I do leave air space in the packets so there is room for expansion.
