Prep the cucumber, carrots, and lettuce. Refrigerate until ready to use.
To make the chicken: Cut the chicken into small chunks. Add to a bowl and toss in lemon juice. Refrigerate for at least 10 minutes. In a small bowl, mix together the hot sauce, honey and lime juice. Set aside.
Coat a large nonstick pan with cooking spray. Heat the pan over medium-high heat. Add the chicken and lemon juice and saute, stirring often, for about 3-4 minutes until chicken is no longer pink. Stir in the hot sauce-honey mixture. Simmer until sauce reduces and thickens a bit, about 4-5 minutes. Refrigerate if serving later and reheat before serving.
To assemble each wrap: Place ¼ cup chicken and a little sauce in each lettuce leaf. Add some cucumber, carrots, and drizzle with ½ tablespoon ranch dressing.
