Preheat grill over medium heat. Prepare chicken mixture. In a medium bowl, combine ground chicken, mayo, garlic, onion and bread crumbs. This is easiest with your hands. Measure out 1/4 cup servings of chicken mixture and flatten into mini patties.
Sprinkle a dash of salt and pepper on both sides of chicken patties, similarly to seasoning a steak.
Grill burgers 3-4 minutes per each side until well cooked. In the meantime prepare slaw. Mix white wine vinegar, olive oil and honey in small bowl Whisk well. Toss in slaw mix and toss to coat. Mix 1/2 cup mayo and 1-2 tbsp hot sauce in a separate bowl. Whisk well and set aside.
When patties are cooked, grill brioche bun halves, 30 seconds per side. Assemble sliders by topping bottom half of bun with a scoopful of slaw. Top with chicken. Spread spicy mayo on top half of bread and place gently on top. Serve and enjoy!
Notes
I love adding a smear of mayo on the brioche buns before grilling them. It gives the best taste to the bread and makes the bread taste even fresher!
