Ingredients

2 1/4 pounds top round of beef, cut into twelve 3-ounce steaks

Olive Oil-Herb Marinade

1 small red onion, cut into paper-thin slices

3 tablespoons red-wine vinegar

Coarse salt and freshly ground pepper

6 ounces baby arugula (or chopped arugula)

2 ribs celery, very thinly sliced on the bias

1 tablespoon freshly squeezed lemon juice

1 tablespoon extra-virgin olive oil

1/4 cup capers, rinsed and drained

Preparation

Cut open two sides of a resealable plastic bag. Place 1 steak in bag; pound to 1/4-inch thickness with a meat pounder. Transfer to a large baking dish. Repeat with remaining steaks. Add marinade. Chill 2 hours.

Place onion in a small bowl with red-wine vinegar, and season with salt; toss to combine.

Heat a grill or grill pan. Place arugula, celery, lemon juice, and olive oil in a medium bowl; toss to combine. Season with salt and pepper. Remove meat from marinade; discard marinade. Season meat with salt and pepper. Grill until browned, about 1 minute on each side. Place two pieces of beef on each plate; sprinkle with capers. Top with arugula salad and pickled onions.
