Tofu Steaks with Shiitakes and Veggies is a quick vegetarian entrée full of flavor and rich vegetables. Piercing the tofu with a fork allows the sesame oil and soy sauce to absorb into the tofu, making it more flavorful.
1. Cut tofu in half crosswise and again in half lengthwise. Pierce tofu liberally with a fork. Place in a shallow dish. Combine 1 tablespoon oil and 1 tablespoon soy sauce in a small bowl. Pour soy mixture over tofu; let stand 15 minutes, turning once. Set aside.
2. Heat a large nonstick skillet over medium-high heat. Add 1 tablespoon oil; swirl to coat. Add bell pepper, carrot, and salt; sauté 3 minutes. Remove from pan. Add remaining 1 tablespoon oil; swirl to coat. Add garlic and mushrooms; sauté 4 minutes. Add remaining 2 tablespoons soy sauce, broth, and next 3 ingredients. Simmer 3 minutes or until thickened. Remove from heat.
3. Remove tofu from marinade; reserve marinade. Heat a grill pan over high heat. Coat pan with cooking spray. Add tofu to pan; cook 3 minutes on each side, basting occasionally with reserved marinade. Arrange 1 tofu steak on each of 4 plates; top each serving with about 1/3 cup carrot mixture and about 2 tablespoons mushroom mixture.
