During the Summer, most cities host some sort of outdoor concert series. New York has Summer Stage in Central Park, in San Francisco's there's Stern Grove, and Chicago's home to Ravinia. While these events are about enjoying music in the open air, the food cannot be overlooked: a scrumptious picnic makes an outdoor concert! So this week pack a basket and head to your local amphitheater.

Steak sandwiches are a portable favorite, and Ina Garten's recipe with sautéed onions, arugula, and mustard mayonnaise will impress your friends. Make use of Summer's ripe tomatoes with a fresh tomato salad. When placed on a bed of watercress and drizzled with a blue cheese dressing, potato salad goes glam. Be sure to keep the salad's three components separate until serving. No picnic is complete without fruit, and watermelon cubes are a refreshing treat. To look at these recipes, read more.

Steak Sandwich Recipe

Ingredients

1 (12-ounce) 1-inch thick New York strip boneless beef top loin steak
Kosher salt
Freshly ground black pepper
Olive oil
2 yellow onions, sliced in rings
1/2 teaspoon fresh thyme leaves
1 recipe Mustard Mayo, recipe follows
2 mini focaccia buns, sliced in 1/2
1/2 cup baby arugula

Directions

  1. Season the steak liberally with salt and pepper on both sides.
  2. Heat 1 tablespoon of olive oil in a medium saute pan over high heat until it's almost smoking, then sear the steak on each side for 1 minute. Reduce the heat to low and cook the steak for about 7 to 10 minutes, turning once, until very rare in the middle. Remove to a plate, cover tightly with aluminum foil, and allow to sit for 10 minutes. Slice the steak into strips.
  3. Using the same saute pan, heat 1 1/2 tablespoons of olive oil over medium heat. Add the onion and thyme and saute for 10 minutes, until the onions are brown and caramelized, stirring occasionally.
  4. To assemble the sandwiches, spread a tablespoon of Mustard Mayo on the bottom half of each bun. Place a layer of the steak strips on top of the mayo, sprinkle with salt and pepper, and top with the caramelized onion rings. Place the baby arugula on top of the onion rings, and cover the sandwiches with the top half of the buns.
