I can't wait to try this unique recipe. What could be better than salmon and peaches together? This is from Peach Perfect (Low Fat Recipes) by Sherri Eldridge. It doesn't specify the grill temperature, but I would go with medium to medium-high.
Prepeare grill or preheat broiler. Spray aluminum foil with non-stick oil, then cover grill or broiler pan with foil. Remove any bones in fillets with pliers.
Peel peaches and cut into quarters. Dice enough to make 1/4 cup and put into blender, reserving remaining peach quarters. Add honey, mustard, lemon juice, pepper, and margarine to blender and whip until sauce is smooth.
In a small bowl, mix ginger, grated lemon rind, and brown sugar.
Arrange salmon fillets on grill or broiler with skin side up. Grill or broil 5 minutes, then turn fillets. Baste fillets with sauce. Arrange peach quarters around fillets; sprinkle spiced brown sugar mixture on peaches.
Grill or broil another 5 minutes, until inner flesh is light pink.
