Creating Grilled Buffalo Chicken Sandwiches with Grinder Slaw is straightforward if you follow these simple steps:

1. Marinate the Chicken: Place the chicken breasts in a bowl and pour half of the Buffalo sauce over them. Let marinate for at least 15 minutes.
2. Prepare the Slaw: In a large bowl, combine the coleslaw mix, mayonnaise, apple cider vinegar, sugar, salt, black pepper, garlic powder, and onion powder. Mix well and set aside.
3. Preheat the Grill: Preheat your grill to medium-high heat and lightly oil the grates to prevent sticking.
4. Grill the Chicken: Remove the chicken from the marinade, shaking off any excess. Place the chicken on the grill and cook for about 6-7 minutes per side, or until fully cooked and internal temperature reaches 165°F (75°C). Brush with the remaining Buffalo sauce during the last few minutes of grilling.
5. Toast the Buns: While the chicken is grilling, place the hamburger buns on the grill for about 1-2 minutes, until lightly toasted.
6. Assemble the Sandwiches: Once the chicken is cooked, remove it from the grill and let it rest for a few minutes. Slice the chicken breasts and place them on the bottom half of each toasted bun.
7. Add the Slaw: Generously top the chicken with the prepared grinder slaw.
8. Finish the Sandwich: Place the top half of the bun on the slaw and secure with a skewer if desired.
9. Garnish and Serve: Optionally, garnish with fresh parsley for a pop of color.

These steps will guide you in creating these incredible sandwiches effortlessly.
