Sweet and Sour Green Beans and Onions

adapted from Tracey's Culinary Adventures

1 lb green beans, trimmed

1 Tbsp butter

2-3 large red onions

1 chili pepper (1/2 tsp dried crushed red pepper)

1/3 cup red wine vinegar

3 Tbsp dark brown sugar

Salt and pepper to taste

Steam beans until just tender, about 5 minutes. Then transfer to a plate and set aside.

Melt butter in a lager heavy skillet at hight heat. Peel the onion, chop in half and chop again lengthwise leaving you with larger pieces of onion. Saute until onions begin to soften (3-4 minutes). Add vinegar and sugar and stir until sauce thickens, about 2 minutes. Add in beans; toss to coat and heat through, about 1 additional minutes. Season with salt and pepper.
