This recipe uses 2 pork tenderloins and suggest cooking 7 - 9 hours on low after cutting them in half. Cooking on high would probably cut the cooking time in half. Hope this helps you.
Creole Pork Tenderloin
2 pork tenderloins, about 1 1/2 to 2 lbs total
1/2 cup flour
1 tbsp Creole seasoning
1 small onion, coarsely chopped
1 small green or red bell pepper, coarsely chopped (or a mixture of both)
1 rib celery, sliced
1 package chicken gravy mix
1 can (14.5 ounces) diced tomatoes, undrained
Cut tenderloins in half; dredge in a mixture of flour and the Creole seasoning. Place tenderloins in slow cooker/Crock Pot. Scatter onion, pepper, and celery over the pork. Cover and cook on low for 7 to 9 hours.
