Process in a blender or food processor until well chopped, then set aside:
1 cup roughly chopped parsley (must be fresh - dried will not work)
1/4 - 1/2 teaspoon salt
1/4 - 1/2 teaspoon red chili pepper flakes
1/8 cup olive oil or canola oil
2 tablespoons sherry wine vinegar or red wine vinegar
2 garlic cloves, halved
1/4 teaspoon black pepper
1 tablespoon chopped onion or scallion
2 tablespoons lemon juice
Preheat the broiler.
Cut the tofu crosswise into slices about 3/4" thick and pat dry with paper towels.
Spray a broiler pan with cooking spray. Place the tofu slices on the pan and spray them with cooking spray.
Mix in a small bowl: 1 teaspoon garlic powder, 1/2 teaspoon paprika, 1/2 teaspoon ground cumin. Sprinkle half the spice mixture over the tofu, turn the tofu over, spray and sprinkle again.
Broil the tofu 3-5 minutes until golden brown, turn over and broil another 3-5 minutes.
Serve drizzled with the chimichurri sauce.
