To make the slaw, combine mayo, rice vinegar, sesame oil and ginger in a large mixing bowl. Whisk together. Add red cabbage, carrot and scallions. Mix well. Set aside.
To make the shrimp glaze, combine honey, soy sauce, sriracha, sesame oil, garlic powder and ginger. Mix well. Reserve a small amount for drizzling after grilling the shrimp.
Preheat grill to high heat. Clean and oil grates.
Thread shrimp onto skewers (make sure to have soaked skewers in water for 30 minutes, if using wooden skewers, to prevent them from burning). Pat dry with a paper towel. Brush lightly with extra virgin olive oil (you don't want it dripping with oil) and sprinkle with salt and pepper on both sides.
Reduce grill heat to medium high. Add the shrimp and grill for 1-2 minutes on each side until shrimp are cooked through and opaque. Before shrimp are cooked through, brush on both sides with the glaze 2-3 times. Remove from grill.
To assemble the sliders, spread each brioche bun with sriracha mayo. Top with grilled shrimp. Drizzle a bit of the reserved glaze overtop the shrimp. Top shrimp with slaw. Sprinkle with sesame seeds, if desired. Serve with remaining slaw.
