Serves two (adjust as needed)
Two medium potatoes
1/2 sweet onion
1/4 cup olive oil
2 tbsp. balsamic vinegar
Two cloves garlic, squeezed
1/4 cup Parmesan cheese, or dried Italian cheese blend
1 tsp. Greek seasoning
Dice the veggies. Put them in a gallon zip-lock bag. Add the rest of the ingredients. Close the bag and shake vigorously to mix.
Your grilling options are either to use a Teflon vessel or triple-folded aluminum foil with PAM sprayed on it. Either way, grill for about ten minutes over a hot fire, stirring every couple of minutes. Test by trying a piece of potato. When it's tender, it's done.
An EXCELLENT accompaniment to any grilled meat.
