Prepare rice according to package directions, omitting salt and fat.
While rice is cooking, heat oil in a nonstick skillet over medium-high heat. Add onion and bell pepper; sauté 4 minutes or until tender. Stir in curry, coriander, turmeric, and salt; cook 2 minutes. Add soy sauce and the next 4 ingredients (soy sauce through tofu). Bring to a boil; reduce heat, and simmer for 2 minutes or until thoroughly heated. Serve the tofu mixture over rice, and sprinkle with cilantro and cashews.
