To make the Asian butter, in a small pot melt the butter (or melt the butter in a small bowl in the microwave). Add the garlic, ginger, sesame oil, soy sauce, and chile-garlic sauce (sambal). Mix to combine.
Place 4 pieces of aluminum foil (about 12 x 18 inches each) on the kitchen counter. Place the salmon on the center of the foil. Place the carrots and snow peas next to the salmon.
Season the salmon and vegetables lightly with salt and pepper.
Spoon the Asian butter over the salmon and vegetables. Sprinkle the scallions over the salmon. Fold the sides of the foil over the salmon and seal the packages completely.
Place the foil packets on a sheet pan and bake for 12 to 15 minutes or until the salmon is cooked through but still a bit pink in the middle.
Transfer the packets to a plate, open and garnish with scallions (optional). Enjoy!
