GRILLED MARINATED FLANK STEAK

Steps:

• Marinade: Into a zip-top bag, add ketchup, soy sauce, brown sugar, onion powder, ground ginger, and Worcestershire sauce. Trim away the root end of garlic cloves, smash with the flat side of a knife, and discard the peel. Smash again, then roughly chop and add to the bag. Close the bag and mix the marinade. Makes about 1¼ cups. (Marinade will keep for up to 1 week in the refrigerator and up to 1 month in the freezer.)
• Steak: Place steak into the bag with the marinade. Press out as much air as possible, seal the bag, and distribute the marinade around the meat. Let marinate for at least 1 hour at room temperature or, optimally, up to 8 hours to overnight in the refrigerator. (Note: If grilling after 1 hour of marinating, reserve the marinade to baste the steak during grilling.)
• If the steak has been marinating in the refrigerator, bring it to room temperature before grilling, about 1 hour.Preheat grill pan (or outdoor grill) to medium-high heat. When grill pan is smoking hot, remove steak from marinade and lay it flat on the grill. Let cook for 4-5 minutes, largely undisturbed, pressing down on the meat to enhance grill marks if you wish. After 4-5 minutes, the steak should be lightly charred and no longer adhere to the grill. Lift and rotate steak about 60 degrees to create cross-hatched grill marks; let cook another 2-3 minutes. Finally, flip and repeat process on the other side, 7-8 minutes. (Total grilling time will be 15-16 minutes.)
• After 15-16 minutes, steak should be medium-rare. Meat should feel firm to the touch at the thickest part (alternatively, a meat thermometer should register 125 F at the thickest part of the steak). Transfer steak to a wire rack fitted over a rimmed baking sheet. Let rest to allow the juices to redistribute in the steak, 15 minutes.
• After the steak has rested, transfer to a cutting board. Find the grain of the meat, then thinly slice against the grain on a bias. Garnish with cherry tomatoes and greens, and serve immediately.
