Grilled Chicken Sandwiches with Pickled Squash and Romesco Mayonnaise

What Makes It Great: The satisfying snap of quick-pickled squash plays well with creamy-smoky red bell pepper mayo, peppery arugula, and savory chicken. Use a mandoline to get perfectly uniform, thin slices of squash. Or for delicate squash ribbons, shave the squash lengthwise with a vegetable peeler.

  • Yield: Serves 4 (serving size: 1 sandwich)
  • Hands-on: 20 Minutes
  • Total: 40 Minutes


  • 1/4 cup cider vinegar
  • 1/4 cup water
  • 1 1/4 teaspoons salt, divided
  • 1 teaspoon sugar
  • 1 thyme sprig
  • 1 (5-ounce) yellow summer squash, very thinly sliced
  • 1/4 cup canola mayonnaise
  • 1/2 teaspoon smoked paprika
  • 1/8 teaspoon ground red pepper
  • 3 ounces bottled roasted red bell peppers, rinsed and drained
  • 1 ounce blanched almonds, toasted
  • 4 (4-ounce) skinless, boneless chicken breast cutlets
  • 1/4 teaspoon freshly ground black pepper
  • Cooking spray
  • 4 (2-ounce) focaccia rolls, halved and toasted
  • 2 cups arugula


1. Combine vinegar, 1/4 cup water, 1 teaspoon salt, sugar, and thyme in a saucepan. Bring to a boil, stirring until salt and sugar dissolve. Pour hot mixture over squash in a bowl. Let stand for 30 minutes, tossing occasionally. Drain.

2. Combine mayonnaise and next 4 ingredients (through almonds) in a mini food processor; process until smooth. Set sauce aside.

3. Heat a grill pan over medium-high heat. Sprinkle chicken evenly with remaining 1/4 teaspoon salt and black pepper. Coat pan with cooking spray. Add chicken to pan; cook 4 minutes on each side or until done.

4. Spread about 2 tablespoons sauce on bottom half of each roll. Top each with one chicken cutlet, about 1/3 cup squash, 1/2 cup arugula, and top half of roll.
