Preheat oven to 400F
Combine coriander, brown sugar, chili powder, Sriracha sauce in a small bowl. Season with salt. Pat salmon dry and rub mixture into both sides of fish, including skin. Let sit for 15 minutes. In the meantime make the salad.
Heat 2 tablespoons olive oil in large non-stick ovenproof skillet over medium-high heat until nearly smoking. Sear salmon fillets skin-side up 2 minutes. Flip, then transfer skillet to oven and cook 7-10 minutes more or until salmon is just cooked through. (depending on thickness) Be careful not to overcook. Mine took 7 minutes and my oven tends to run hot.
Good salmon is expensive so if unsure, use a thermometer. It makes life so much easier!
