Heat oven to 450°F. Spray shallow roasting pan and rack with cooking spray. Place pork tenderloins on rack in pan.
In small bowl, mix remaining ingredients. Spoon herb mixture evenly over pork. Insert ovenproof meat thermometer so tip is in the thickest part of pork. Cover pork loosely with foil.
Bake 20 minutes; remove foil. Bake uncovered 10 to 15 minutes longer or until thermometer reads 155°F. Cover pork loosely with foil and let stand 10 to 15 minutes or until thermometer reads 160°F. (Temperature will continue to rise about 5°F, and pork will be easier to carve.)
