1 pork tenderloin
1/2 lb. bacon, sliced
1 c. low-sodium soy sauce
1/2 yellow onion, minced
3 cloves garlic, minced
2 tbsp. vinegar (not balsamic)
1/2 to 1 tsp. cayenne pepper
1 tsp. sugar or sugar substitute

Wrap pork tenderloin in bacon. Combine next 6 ingredients and pour over bacon wrapped pork tenderloin. Marinate 2 hours to overnight (turning in marinade occasionally). Remove wrapped tenderloin from marinade (reserve marinade). Roast/bake in a 300°F oven or grill on barbecue until tenderloin registers done on a meat thermometer. (Varies by cut/size of tenderloin and/or preference of doneness, i.e., medium-rare, etc.)
