Roasted Green Beans 1 lb green beans, washed and stemmed 1 red onion, cut in half and sliced into semi-circles roasted red bell peppers (roast your own, or use jarred), - sliced into strips balsamic vinegar salt and pepper, or other seasonings - (I used a bit of garlic powder, thyme and sage.) Spread green beans and onions in a Pammed baking dish. Place in a 400 degree F oven and roast approximately 20 minutes, or until beans are as tender as you like. Shake the pan a few times while roasting, and add a few ts water or stock if they appear to be getting too dry. When ready, empty into a bowl, add roasted peppers and a few splashes of balsamic vinegar. Stir well. Season to taste, and chill (can also be served warm).
