This recipe is super flexible! Use any veggies you like—snap peas, baby corn, or mushrooms all work. For a vegetarian version, substitute firm tofu for the chicken. Store leftovers in the fridge up to 4 days, or freeze up to 2 months. To reheat, warm in a skillet with a splash of broth or microwave until heated through. For more heat, add dried chilies or extra chili paste.
