Position an oven rack about 6 inches from the broiler and preheat the broiler to high.
Rub each salmon fillet all over with the sesame oil and season lightly with the pinch of kosher salt.
Heat a cast-iron skillet over medium-high heat until hot but not smoking.
In a small bowl, whisk together the honey, sambal oelek, soy sauce, grated ginger, chopped garlic, lime zest and the 2 tablespoons lime juice, and rice vinegar.
Pour the sauce into the hot skillet and bring to a gentle boil for 2–3 minutes, stirring, until slightly thickened.
Remove the skillet from the heat and place the salmon fillets in the pan, skin side up so the glaze coats the top.
Transfer the skillet to the oven and broil for 2–3 minutes, watching closely, until the salmon is cooked through and the skin is crisped to your liking.
Meanwhile, in a medium bowl combine the shredded purple cabbage, sliced nectarines, chopped cilantro, shredded carrots and chopped jalapeños; toss with any remaining lime juice or a splash of rice vinegar if desired.
Serve each salmon fillet topped with the slaw and spoon any extra pan sauce over the fish.
