Tandoori Tofu

Preheat grill to medium-high.

Combine paprika, 1/2 teaspoon salt, cumin, coriander and turmeric in a small bowl. Heat oil in a small skillet over medium heat. Add garlic, lime juice and the spice mixture; cook, stirring, until sizzling and fragrant, about 1 minute. Remove from the heat.

Slice each tofu block crosswise into 6 slices; pat dry. Use about 3 tablespoons of the spiced oil to brush both sides of the tofu slices; sprinkle with the remaining 1/2 teaspoon salt. (Reserve the remaining spiced oil).

Oil the grill rack (see Tip). Grill the tofu until it has grill marks and is heated through, 2 to 3 minutes per side.

Combine yogurt with the reserved spiced oil in a small bowl. Serve the grilled tofu with the yogurt sauce, garnished with scallions (or cilantro), if desired.
