To make the slaw, in a medium-sized bowl combine cabbage with onion, ranch dressing, salt, and pepper. Toss to combine, taste for seasonings and adjust to your preference.
To make the burgers, in a large bowl, combine ground chicken with almond meal or breadcrumbs, mayonnaise, garlic, onion powder, smoked paprika, buffalo sauce, and green onions. Use your hands to combine well, but do not overwork to get a better texture.
Divide the mixture into 4 or 6 portions, and gently flatten and shape into patties that are about half an inch thick.
If using the stovetop, heat oil in a pan over medium-high heat and add the patties to the pan. Cook on both sides for about 10 minutes or until the internal temperature of the patties is 165°F/74°C.
If using the grill, preheat the grill to medium heat (around 350°F/180°C). Clean and oil the grill grates. Cook the patties for about 10 minutes on both sides until the internal temperature of the chicken is 165°F/74°C.
To serve: Slice the buns in half, and toast the cut side until golden and crispy. Spread a little bit of ranch on the bottom half bun, add the patty, drizzle buffalo sauce, and top with slaw and the other bun.
