Ingredients

Instructions

  1. Step 1: In a small bowl, whisk together 1/3 cup white vinegar, 1/3 cup water, and 1 tbsp sugar until sugar dissolves. Add 1/2 thinly sliced red onion and let sit for at least 20 minutes to pickle.
  2. Step 2: Preheat grill or grill pan to medium-high heat. Rub 2 boneless skinless chicken breasts with 2 tbsp olive oil, 1 tsp smoked paprika, 1 tsp salt, and 1/2 tsp black pepper.
  3. Step 3: Grill chicken for 5-6 minutes per side until internal temperature reaches 165°F and juices run clear. Remove and rest for 5 minutes.
  4. Step 4: Meanwhile, mix 1/4 cup mayonnaise with 1 tbsp sriracha sauce and 1 minced garlic clove in a small bowl to make spicy aioli.
  5. Step 5: Toast 2 burger buns lightly on the grill. Slice chicken breasts thinly and assemble sandwiches with 2 lettuce leaves per bun bottom, sliced chicken, pickled onions (drained), and a generous spread of spicy aioli. Top with bun halves and serve.
