• 1 Tablespoon olive oil
• 1 Teaspoon balsamic vinegar
• 1 Tablespoon white sugar
• 1 large onion, sliced
• 2 Tablespoon softened margarine, softened
• 1/4 Cup Parmesan cheese
• 4 Slices Swiss cheese
• 8 Slices bread

1. Pour olive oil, sugar and vinegar into a medium hot skillet. Add onions and caramelize 30 minutes, stir frequently. Mix margarine and Parmesan cheese and spread onto the bread slices. When onions are a deep brown color, remove from heat. Place bread, one at a time in skillet, margarine side down. Add Swiss cheese and a fair portion of the onions and close with another slice of bread, margarine side out. Brown both sides.

With a nice sweet onion to blend with the creaminess of the cheese, you receive a great flavor. $$$Cost per Serving: $0.92, Recipe Cost $0.92
