INSTRUCTIONS
1. Cut 1/2-inch crosshatch pattern, ¼ inch deep, on both sides of steak. Place steak in 1-gallon zipper-lock bag. Combine soy sauce, vinegar, ketchup, sage, garlic, oil, and rosemary in blender and process until garlic and herbs are finely chopped, about 30 seconds. Add marinade to bag with steak, seal, and turn to coat. Let sit at room temperature for 2 hours or refrigerate for up to 8 hours. (If refrigerated, bring steak to room temperature before grilling.)
2. Turn all burners to high, cover, and heat grill until hot, about 15 minutes. Leave all burners on high.
3. Combine pepper and paprika. Remove steak from marinade, pat dry with paper towels, and season with pepper mixture.
4. Clean and oil cooking grate. Grill steak (over hot side of grill if using charcoal) for 1 minute. Flip and grill on second side for 1 minute. Repeat, flipping every minute, until steak registers 125 degrees for medium-rare, 5 to 7 minutes, or 130 degrees for medium, about 9 minutes. Transfer to carving board, tent loosely with aluminum foil, and let rest for 10 minutes. Thinly slice steak against grain. Serve.
