Make the sauce by combining all ingredients in a medium saucepan over medium/low heat. Stir occasionally until sauce begins to boil, then simmer uncovered for 15 minutes or until syrupy. Watch the sauce closely to be sure it doesn't bubble over. Preheat barbecue grill to medium heat. Rub each salmon filet with vegetable oil, then add a light sprinkling of salt and pepper. Grill the salmon for 4 to 7 minutes per side or until done. Serve salmon with a small cup of the honey pepper sauce on the side.
