Caramelized Onions and Bell Peppers Recipe

Heat the oil in a large skillet over medium-high heat. Add the onions, peppers, salt and pepper.

Reduce the heat to medium-low and cook, 15 to 20 minutes, stirring frequently, until the onions are caramelized and the peppers are tender and slightly browned. If a brown coating forms on the bottom of the pan during the cooking process, add a few tablespoons of water and stir; repeat as necessary.

Add balsamic vinegar and thyme and turn the heat down to low. Cook for a few more minutes.

Taste and adjust seasoning, if necessary. Serve hot or at room temperature.
