Preheat oven to 350°. Cut the onions in half from root to tip (remove outer skin). In a bowl, coat onions with the Cherry Balsamic Sauce. Lay cut-side down in a lightly oiled baking pan.
Bake for about 20 minutes and remove pan from the oven; turn onions cut-side up. Pour more Cherry Balsamic Sauce over onions and return to the oven. Cook for another 25-30 minutes until onions are glazed and caramelized.
Remove to serving platter and drizzle with Cherry Balsamic Sauce and top with lightly toasted pine nuts. (Do not reuse the sauce from the baking pan as it “may” have a slightly burnt taste). Serve warm as a side dish with your favorite steak, pork chop, or grilled chicken. The onions can also be served cold on a leaf lettuce salad.
