--------  ------------  --------------------------------
   2      medium        red onions -- halved
   5      tablespoons   virgin olive oil
   8      ounces        balsamic vinegar
  12      ounces        raw trumpet mushrooms
     1/4  cup           sundried tomatoes in fine julienne
   3      ounces        white truffle oil
                        zest and juice of 1 lemon
                        salt -- to taste
                        freshly-ground black pepper -- to taste

Preparation:

Preheat oven to 450 degrees. In a medium 10-inch sauté pan, heat virgin olive oil over medium heat. Place onions cut-side down and sauté, moving often until golden brown (about 8 to 10 minutes). Pour vinegar into pan and place in oven to bake for 20 to 25 minutes until quite soft. Check after 10 minutes to be certain there is still liquid in the pan. If not, add 1/2 cup cool water. When soft, remove from oven and let cool. When onions are cool, remove from pan and cut each half into quarters, removing peel. Set aside in a large mixing bowl. Into the same mixing bowl, place trumpet mushrooms, sundried tomatoes, truffle oil, zest and juice of a lemon and toss together. Season with salt and pepper and divide among 4 plates and serve.
