1. Slice pork lengthwise down center, cutting to, but not through bottom. Press with hands to flatten pork. Sprinkle sage and lemon-herb seasoning over pork. Combine apricot spread and mustard. Spread half of apricot mixture over pork.
2. Prepare grill.
3. Coat grill rack with cooking spray, and place on grill over medium-hot coals (350° to 400°). Place tenderloins on rack; grill, covered, 7 minutes. Turn pork, and baste with remaining apricot mixture. Cover and grill 7 additional minutes or until a meat thermometer inserted into thickest part of tenderloin registers 160°.
