Prepare Marinated Tofu, and set aside. Heat olive oil in a large skillet over medium heat, and add onions. Cook until onions are soft and translucent.
Add reserved marinade from tofu, broccoli, carrots, garlic, tahini, and ginger. Cook, covered, for 8-10 minutes or until vegetables are tender crisp, stirring frequently.
Add pineapple juice, rice and walnuts, and cook until heated through and juice is nearly absorbed. Sprinkle with sesame seeds. Stir, and serve.
