Roasted Green Beans with Peppers and Onions

A friend reminded me this morning that I served this last year for Thanksgiving dinner. It was so good, I plan to serve it again this year.

Toss together in large roasting pan:

1 lb. whole frozen or fresh green beans, ends trimmed
1 red pepper, cut into thin strips
1 yellow pepper, cut into thin strips
1 large onion, cut into thin strips
1/2 cup Balsamic Vinaigrette Dressing

Bake 30 minutes or until vegetables are tender, stirring after 15 minutes.

Sprinkle with:
1/2 cup shredded mozzarella cheese

Bake an additional 2 to 3 minutes or until cheese is melted.
Serves 6.
