I'm going to make apples and sweet potatoes on the grill. I got the recipe from allrecipes.com, but I don't remember amounts or anything.
2 sweet potatoes diced
1 apple, peeled and sliced
ginger (I'm adding ginger...I just like it)
mix everything in a bowl and wrap into 2 or 3 foil packets. Grill over medium heat about 20 minutes (or until sweet potatoes are soft) turning every 5-7 minutes.
