Zuni Burgers

Ingredients

1. 1 3/4 pound boneless beef chuck, cut into 3-by-1-inch strips
2. Fine sea salt
3. Freshly ground pepper
4. 4 squares of focaccia, split
5. Slices of tomato and red onion

1. In a bowl, toss the meat with 1/2 teaspoon salt. Cover with plastic and refrigerate overnight.
2. Coarsely grind the meat in a grinder and shape into 1 1/4-inch-thick patties; work quickly so that the meal remains chilled.
3. Light a grill or heat a grill pan or a cast-iron skillet. Season the burgers with salt and pepper and grill or pan-fry over moderately high heat, turning once, about 4 minutes per side for medium-rare or until done to your liking. Let rest for 2 minutes, then serve with the focaccia with the tomato and red onion.
