Prepare the slaw by whisking mayonnaise, Sriracha, lime juice, and honey in a bowl; fold in the cabbage until coated and refrigerate.
Using a sharp chef's knife, finely chop the salmon into 1/4-inch pieces.
In a large mixing bowl, combine the chopped salmon, panko, egg, mustard, dill, salt, and pepper; mix by hand until just incorporated.
Form the salmon mixture into four equal patties, approximately 4 inches in diameter and 1 inch thick.
Heat olive oil in a non-stick skillet over medium-high heat.
Sear the patties for 3 to 4 minutes per side until the exterior is golden brown and the internal temperature reaches 145°F (63°C).
Place each patty on a toasted bun base, top with a generous portion of Sriracha slaw, and cover with the bun top.
