Spritz the aluminum foil with nonstick cooking spray.
Drizzle olive oil over the chicken and toss to coat.
Spread the chicken pieces over the baking sheet.
Season the chicken breasts with salt and pepper on both sides.
Place the baking sheet into the oven and broil the chicken for about 3 to 4 minutes per side, or until cooked through and no longer pink in the center.
Remove from heat and let rest for a few minutes.
In a small bowl, whisk together honey, Dijon mustard, mayonnaise, olive oil, lemon juice, and minced garlic to make the honey mustard dressing. Set aside.
Warm the flour tortillas in the microwave for about 20 seconds to make them pliable.
To assemble each wrap, layer shredded lettuce, diced tomatoes, diced red onions, chicken, and dressing.
Roll up the tortilla tightly, folding in the sides as you go, to form a wrap.
Secure the wrap with toothpicks if needed, then slice in half diagonally. Serve immediately.
