Preheat oven to 400 degrees F. Cut sweet potatoes into 1/4x1/4x3 inch spears. Place in 9x13 inch casserole. Add 2 cups brown sugar, lemon juice, and 1/2 cup cooking wine. Bake in oven for 25 minutes, basting several times.

While potatoes cook, melt butter in saute pan. Add onions, 2 Tbsp. brown sugar, seasonings, and green beans. Saute for 2 minutes; add cooking wine and continue to saute until desired tenderness of vegetables. Remove from heat and keep warm.

Remove sweet potatoes from any remaining basting liquid; toss with green beans and serve.
