Look for sesame-ginger stir-fry seasoning sauce in the grocery store's Asian foods or sauces and marinades section. Brands vary by sweetness and spice level.
Look for stir-fry vegetables with precut vegetables in the grocery store's produce department.
Use your favorite vegetables in place of prepared stir-fry vegetables; try bean sprouts and shredded napa cabbage with bite-sized pieces of green onion, broccoli, carrots, mushrooms and pea pods; measure 4 cups. Or swing by the salad bar and choose 4 cups of cut vegetables.
