Carmelized Onions

These are a great side to add to any meal.  

2 tsp olive oil

2 sliced onions

2 tsp sugar

2 tsp balsamic vinegar

1/4 tsp dried thyme

1/4 tsp salt

dash of pepper

In a large nonstick skillet coated with cooking spray, heat oil over medium-high heat.  Add onion, sugar, thyme, salt, pepper, and vinegar, and cook, stirring, until sugar dissolves.  Reduce heat to medium-low, cover, and cook until golden brown, about 20 - 30 minutes, stirring occasionally.
