Make the bang bang sauce. Add all of the sauce ingredients to a medium bowl. Mix until smooth, then set aside.
Heat the griddle or skillet on medium heat. *For griddle cooking, aim for a temperature of about 375℉.
Prep the salmon. Place the fresh salmon filets skin-side down on a platter. Brush the flesh side of each filet with a small amount (about ½ tablespoon) of sweet chili sauce. Then sprinkle with your all-purpose seasoning or salt and black pepper.
When the griddle or skillet is hot, add about 1-2 tablespoons cooking oil. Then place the salmon flesh side down on the oiled surface. Cook on the first side for about 3-4 minutes, then flip to the skin side and cook an additional 3-4 minutes. *TIP - Keep an eye on the heat—sweet chili sauce can burn, so once you get a nice sear, flip promptly. If needed, place a melting dome or the skillet lid over the salmon after flipping to speed up the cooking time and encourage even heating.
Cook the salmon until the internal temperature reaches about 125-130℉, or until the salmon is almost done to your liking. If needed, flip the fish filets again so that they cook evenly. Then brush the salmon generously with your bang bang sauce as it finishes cooking.
Continue to cook the salmon, brushing a few times with the bang bang sauce, until the fish is done to your liking. Then plate and serve immediately. You can also add a bit more sauce on top. *See notes on total cooking time and temperature.
