Combine chicken, breadcrumbs, milk (or water), garlic, half the scallions, the paprika, salt, pepper, and egg in a large bowl with a fork, mixing until just combined. Transfer bowl to fridge while you prepare the slaw.
Remove chicken meatball mixture from fridge and, using wet hands for a smoother shape, form 6 patties (about 1/3 pound each). Sprinkle the tops with salt and pepper.
Heat a large frying pan over medium-high heat (I like to use cast iron but any non-stick skillet works well), then coat with about 2 tablespoons oil when it's hot. Place your first three burgers in the pan and let them cook for about 6 minutes until starting to cook through on the outside edges, and the first side is done. Season the tops with an extra dusting of salt and pepper again, and then flip for another 4-5 minutes - you want them relatively crisp and browned on the outside, and cooked through in the middle (165 degrees on a meat thermometer).
Meanwhile, toast the buns so they are ready when the burgers are done - I like to spread butter on the insides of the buns before toasting. You can also do all of this on the grill...
When the burgers are cooked through, place each on a toasted bun bottom, and top with a thick spreading of your favorite BBQ sauce.
SLAW
Whisk buttermilk, mayo, cider vinegar, sugar, and remaining half of scallions in a large bowl and add cabbage, and carrots, tossing to evenly coat it. Season to taste with celery salt and pepper (you can also use regular salt, but celery salt gives it a great flavor).
FINAL ASSEMBLY
Top each BBQ sauce covered chicken burger with a heaping mound of your delicious coleslaw, add a few pickles, and crack open a beer. ENJOY!
Notes
This recipe is a slightly tweaked version of Smitten Kitchen's Smashed Chicken Meatball Sliders, which you can find here. https://smittenkitchen.com/2023/05/smashed-chicken-meatball-sliders/. I have increased the size of the burgers to be full size, and changed a few ingredients, but it's an amazing base recipe.
