Gluten-free The combination of heat from the chipotles and citrus from the orange and lemon juices makes a flavorful sauce that packs a punch for the broccoli and tofu. This can be enjoyed alone or served over rice or quinoa; and, of course, you may substitute another vegetable for the broccoli (cauliflower or asparagus are good choices) or use seitan, tempeh, or cooked beans in place of the tofu.
