Green Beans with Caramelized Onions

1 Pound of Fresh Green Beans, ends trimmed
2 Tablespoons of Butter
1 - 2 teaspoons Balsamic Vinegar
2 sweet Walla Walls Onions
2 Tablespoons Brown Sugar

Bring enough salted water to a boil to cover the green beans in a saucepan. Add the green beans and cook for 10 minutes. Drain and rinse with cold water to stop them from cooking. You can chill them in the refrigerator for up to a day at this point and then finish the salad the next day.
Cut Onions in thin slices and cut each slice in half. Melt the butter in a large non-stick pan over medium-high heat. Add the onions and cook for 10-15 minutes until the onions are golden brown, stirring frequently. Reduce heat to medium and stir in the brown sugar. Add Vinegar and mix well. Add the green beans and cook until beans are heated through.

Supper Club: follow all the steps, but after cooking the onions and vinegar do not add beans. Allow onion mixture to cool, then place in microwavable or oven safe serving dish with the green beans. When you get to the host house you can microwave until heated through or place in a low temp oven for 10-15 minutes.
