35-minute recipe Serves 4


Prep: 20 mins | Cook: 15 mins
  • 1

    Combine red peppers, almonds, oil, vinegar, garlic, 1/4 tsp each pepper and salt and paprika in a food processor. Pulse until evenly chopped. Set Romesco sauce aside.

  • 2

    Pat flank steak dry with paper towel. Season with remaining 1/2 tsp pepper and 1/4 tsp salt.

  • 3

    Preheat barbecue to medium-high.

  • 4

    Oil grill. Barbecue steak, flipping halfway, until an instant-read thermometer inserted to the thickest part reads 145°F for medium rare, 10 to 12 minutes. Transfer to a cutting board, cover with foil and let rest for 10 minutes. Slice steak thinly against the grain.

  • 5

    Fill buns with kale, olives, steak slices, Romesco sauce and cheese.

  • 6

    Lower barbecue to medium. Place sandwiches on grill and barbecue until buns are toasted and cheese is melted, 2 to 3 minutes.
