This easy stir-fry works with any sort of cabbage. Bok choy, brussel sprouts or broccoli would be perfect alternatives. If you like, make an extra batch of sauce as a marinade for firm tofu cubes. Marinate the tofu for 15 minutes or so, then stir-fry the cubes (discarding the marinade) in hot oil before you cook the vegetables—until they turn golden-brown and slightly crunchy on the outside. Set the tofu aside while you cook the veggies, then add it back in with the nuts and peas. Serve over rice or cooked spaghetti noodles or by itself as a side dish.
