Instructions

• Heat a grill to medium-high heat. Place the chicken breasts on a baking sheet or large dish and pat dry. Drizzle lightly with olive oil and rub the chicken to coat evenly.
• Sprinkle half of the Cajun seasoning over the tops of the chicken breasts, turn the chicken over, and sprinkle the remaining half of the Cajun seasoning on the bottom side of each breast so the chicken is evenly coated.
• Place the chicken breasts directly over the heated side of the grill and grill for about 5-6 minutes per side, depending on the thickness of your chicken, until the internal temperature reaches 160°F. Remove from the grill and rest for 5 minutes.
• Heat a large pan or griddle over medium heat. Separate the top and bottom buns and spread the cut sides of each bun with a little mayonnaise. Lay each bun mayonnaise side down in the pan or on the griddle and cook until toasty, then remove to a plate.
• Prepare each sandwich with a toasted bun, 1 grilled Cajun chicken breast, and slices of lettuce, tomato, and onion, along with additional mayo or aioli. Add cheese if you would like. Serve immediately!
