Preheat your air fryer to 350°F (175°C). Place the ½ cup sliced almonds in the air fryer basket in a single layer. Toast for 3-5 minutes, shaking halfway through, until golden and fragrant. Remove and set aside to cool.3 cups chicken breast
Season boneless, skinless chicken breasts with salt, pepper, and olive oil. Preheat your air fryer to 375°F (190°C). Place the chicken breasts in the air fryer basket and cook for 12–15 minutes, flipping halfway through. Ensure the internal temperature reaches 165°F (75°C). Let the chicken rest before chopping into bite-sized pieces.
In a small bowl, whisk together the mayonnaise, lemon juice, honey, apple cider vinegar, ground mustard, onion powder, rosemary, salt, basil, and black pepper until smooth.
In a large bowl, combine the cooked chicken, toasted almonds, diced celery, and halved grapes. Pour the dressing over and mix gently until well-coated.
Lay out the sourdough bread slices. Layer the chicken salad, tomato slices, and green leaf lettuce on one slice of bread. Top with the other slice of bread to make a sandwich.
Cut the sandwich in half and serve immediately. Alternatively, enjoy the salad on its own or as a wrap!
