Prepare Phyllo Tartlets. Cook remaining ingredients except cheese in 10-inch nonstick skillet over medium heat 20 minutes; reduce heat to medium-low. Cook uncovered 50 minutes, stirring occasionally, until all liquid is absorbed and onions are consistency of marmalade. Heat oven to 400°. Fill each tartlet with 2 teaspoons onion mixture. Place on ungreased cookie sheet. Sprinkle each tartlet with 1/2 teaspoon cheese. Bake 6 to 8 minutes or until cheese is light brown. Serve hot.
