Heat pan over medium-high heat. Add sesame oil (or water) and marinated tofu (including any remaining marinade liquid) and cook tofu until brown. Gently flip tofu a few times to ensure even cooking. Remove from skillet and set aside.
Return the same skillet to medium-high heat. Once hot, add sesame oil, mushrooms, cabbage, and bell pepper and stir to sauté veggies. Cover and cook 2-3 minutes, stirring occasionally.
Add garlic, green onion, and ginger. Stir, cover, and cook for another 1-2 minutes.
Move the veggies to one side of the pan. Add cooked grains or cauliflower rice to the other side of the pan. Cover and cook for 2 minutes or until slightly browned.
Return cooked tofu to the pan, add sauce, and stir fry for a few minutes, tossing/stirring occasionally until sauce is well incorporated and all ingredients are hot.
