Saute the vegetables and spices. Whisk together the sauce ingredients. Combine the sauteed vegetables and the sauce and pour over tofu cubes in a shallow baking pan. Bake covered at 350F for 30 minutes and uncovered for another 30 minutes, stirring very gently to avoid breaking the tofu cubes throughout the cooking period. Serve on rice with a side dish of cole slaw or mixed greens. Or pack it into a pita to make a Dixie Pita Sandwich.
