Bell Peppers with Peanuts and Water Chestnuts

I came across this recently. Sounded so good I had to give it a try.
NEED:
3 tablespoons sou sauce ( can use reduced sodium one)
1 tablespoon hoisin sauce ( this is a thick, sweet & spicy sauce with a soybean base--look for it in the international food isle.)
3 tablespoons peanut oil
1 medium yellow bell pepper, cut in 1/4 inch slices
1 medium green bell pepper, cut in 1/4 inch slices
1 medium red bell pepper, cut in 1/4 inch slices
1 can ( 8 ounces) drained water chestnuts
1/2 cup unsalted peanuts
2 garlic gloves, minced ( or 1/2 tablespoon jarred garlic)
2 to 3 cups of cooked rice, optional

Mix together soy sauce and hoisin sauce. Set aside. Hear peanut oil in large skillet over high heat. Add peppers and cook until tender, about 4 minutes. Stir a couple times. Add water chestnuts, peanuts and garlic. Cook 1 minute, stirring constantly. Stir in sauce mixture. Serve over rice id desired.

Enjoy!
