Prepare all ingredients as listed above.
Combine the water and cucumber slices. Refrigerate to infuse.
In a small bowl, combine all ingredients for the hot honey mustard sauce. Mix until well combined, then reserve half of the sauce for serving.
Preheat the air fryer or oven to 400°F (204°C).
Mix the chicken with the remaining half of the sauce until evenly coated.
Place the chicken in the air fryer basket. Cook until the internal temperature reaches 165°F (74°C) for safe consumption, about 12–15 minutes depending on appliance. Slice before using.
Slice the rolls in half and lightly toast them in a toaster oven until golden.
Assemble the sandwiches: Layer the chicken onto the roll. Top with pickle slices and drizzle with reserved sauce. Add the top half of the roll slice in half.
Serve the sandwich alongside carrots, hummus, watermelon, and cucumber water.
