This spiced-up burger is finished with warm, melty blue cheese, and balsamic-soaked red onions lend an extra flavor kick.

4
4 medium onions sliced
2 teaspoon sugar
2 tablespoon olive oil

Cook onions and sugar in hot oil over low heat 20 to 25 minutes until onion is caramelized, stirring often. Stir in the 1/4 cup water, vinegar, and 1/4 teaspoon of the salt. Set aside and keep warm.
