1 teaspoon of oil from oil packed sun-dried tomatoes, or an equal amount of olive oil
1 large or 2 medium sweet onions, peeled, trimmed, halved, and thinly sliced
1 1/2 tablespoons aged balsamic vinegar
Salt and fresh ground pepper to taste
heavy duty aluminum foil

Place the onion pieces into the center of a large piece of heavy duty aluminum foil. Sprinkle with 1 teaspoon of the sun-dried tomato oil or olive oil and 1 1/2 tablespoons of aged balsamic vinegar, then salt and pepper to taste. Mix the ingredients with your hands to make sure the onions are well coated. Bring the two long ends of the foil together and roll it down until tight, then take the ends and roll towards the center to secure the packet.

Place the onion pack on a medium high grill, and cover. If cooking with burgers, let the onions cook by themselves for about 15-20 minutes, then put them to the side of the grill and let them continue cooking while the burgers cook, or about 10-12 more minutes. Remove the grill pack from the heat, open carefully and serve. Makes enough onion for about 4 burgers or 8 sliders.
