Churrasco typically refers to grilled beef, but our tofu steaks are every bit as meaty and satisfying. Be sure to press and drain out as much liquid as possible before cooking the tofu. It will better absorb the spices from the dry rub and reach its full grilling potential. Parsley, cilantro, and hemp seeds unite to create an herbaceous and delightfully zesty chimichurri that brings heavenly depth to the tofu steaks. Hemp seeds offer quality plant-based protein and are a rich source of heart-healthy fats and dietary fiber. Serve this dish with roasted vegetables and crusty whole-grain bread to soak up all the sauce.
Preheat oven to 400°F. Combine parsley, cilantro, hemp seeds, vinegar, lime juice, garlic, red pepper, 1/2 teaspoon salt, and 1/4 cup oil in a food processor; process until smooth. Set aside.
Press tofu with paper towels until very dry. Slice each block in half diagonally. Stand each half on cut side, and split each into thirds, creating 12 equal triangles. Place in a single layer on paper towels.
Combine garlic powder, onion powder, smoked paprika, cumin, black pepper, and remaining 1/2 teaspoon salt in a bowl. Rub spice mixture evenly on each side of tofu steaks. Spray steaks with cooking spray.
Heat remaining 1 tablespoon oil in a grill pan over medium-high. Cook tofu steaks in single-layer batches until deep char marks appear, 3 to 5 minutes on each side. Transfer to a baking sheet.
Bake tofu steaks at 400°F for 5 minutes. Place 2 tofu steaks on each of 6 plates. Top each serving with about 1 tablespoon herb mixture.
