To prepare dressing: Puree carrot, carrot juice, miso, vinegar, oil, ginger and garlic in a blender or food processor until smooth. To prepare tofu: Slice each tofu block crosswise into 5 slices; pat dry with paper towels. Combine honey, oil, soy sauce, black bean-garlic sauce and garlic in a small bowl. Spread half the marinade in a large baking dish and top with the tofu slices. Spread the remaining marinade over the tofu, covering completely. Preheat grill to medium-high. Oil the grill rack. Grill the tofu until heated through, 2 to 3 minutes per side. To serve, toss greens with the dressing. Divide among 6 plates and top with the tofu. Serves 6.
