Rolled Stuffed Flank Steak

Heat broiler, with rack 4 inches from heat. In a large pot, heat 1 tablespoon olive oil over medium-high. Add garlic and cook until fragrant, 30 seconds.

Add greens; cook until wilted, 5 minutes. Stir in soy sauce, sesame oil, and red-pepper flakes. Remove pot from heat.

Place steak between sheets of plastic wrap and pound to 1/2 inch thick with a meat mallet or small skillet.

Spread greens on steak, leaving a 2-inch border on one long side; season with salt and pepper. Roll up toward border.

Tie crosswise with 5 or 6 pieces of kitchen twine. Rub steak with 1 teaspoon olive oil; season with salt and pepper. Place steak, seam side up, on a foil-lined rimmed baking sheet.

Broil 5 minutes. Flip and broil until browned, 5 minutes for medium. Loosely tent with foil and let rest 10 minutes. Slice steak into 1/2-inch rounds.
