Potatoes and Green Beans on the grill

We love these easy potatoes and green beans that are made on the grill. 

4 to 5 red potatoes
2 cups fresh green beans
1 to2 cloves garlic
1/2 cup finely chopped onion
salt and pepper to taste
oil and butter
foil

Wash the red potatoes, then cut in half, and slice them. Wash and trim the grean beans, and cut into pieces. Chop the onion finely, and mince the garlic. Put the potatoes, beans, onion, and garlic in a big bowl and drizzle with a little bit of oil and season with salt and pepper. Tear off a big sheet of foil (the heavy duty works best), you may need two sheets if it is the light weight foil. Put the foil on an old baking pan, turn up the edges of the foil about an inch all the way around so it looks like you have a baking pan made of foil.

Pour out the potatoe mixture on top of the foil, and pour in a little bit of water, about 1/4 cup, and dot with chunks of butter. Cover the potatoes with another piece of foil and put on the grill on low heat for 1/2 hour, checking for moisture after 15 minutes. You may or may not need to add more water during the process as it is important to keep moisture in the foil packet.
