Combine first 3 ingredients, and brush over tenderloins. Cover and chill 8 hours.
Cook, covered with grill lid, over medium-hot coals (350° to 400°) about 20 minutes or until a meat thermometer inserted into thickest portion registers 160°, turning once.
FABULOUS! Even if you are not a cook this recipe wins applause time after time from everyone that eats it. Every time we have served this every one wants the "secret" recipe.
