Mix the Teriyaki sauce, ginger, garlic, and chili powder with the honey. Taste and adjust as desired.
Cut the salmon fillets lengthwise and marinate them in the sauce. Refrigerate for at least 4 hours or overnight.
Remove the salmon from the refrigerator an hour before serving and pat it dry. Bring the marinade to a boil and strain for extra sauce.
Thread two skewers lengthwise through each piece of salmon. This keeps the salmon intact while grilling the brochettes.
Grill the salmon all around on the grill. Serve with lime wedges and sprinkle with sesame seeds.
Tips
Save leftover marinade for extra sauce. For a more intense taste, marinate the salmon overnight.
