I think that most of the bbq sauces have a lot of sugar. Maybe if you have time, you could whip up a sb friendly bbq sauce. I found this doing a google search:
http://wb2.trb.com/news/kwgn-sugar-f...,2492775.story
1 8 oz can tomato sauce, 1/2 cup cider vinegar, 2 tbsp white vinegar, 2 tbsp liquid smoke, 3 tbsp chili powder, 1 tbsp garlic powder, 1 tsp cinnamon, 1/4 tsp nutmeg, 1 tbsp sweetener, like Splenda or Equal (optional, and to taste)
Combine all ingredients at least 1/2 hour before using.
This is enough sauce for 1-2 racks of baby-back pork ribs. Double the recipe as needed. If the ribs are very thick, cut the racks in half and boil them in a stockpot for 20 minutes before BBQ-ing.
Coat ribs with sauce, and grill. Add more sauce as you turn the ribs. Serve with additional sauce if desired. Enjoy!!
edited to add: oops, I didn't read that part. Don't use ribs, really high in fat, use it on a nice chicken breast or something leaner.

Sugar Free Barbecue Sauce
1 sm. onion, minced
1 (8 oz.) can tomato sauce
2 c. water
1/4 c. wine vinegar
1/4 c. Worcestershire sauce
1 tsp. salt (optional)
2 tsp. paprika
2 tsp. chili powder
1 tsp. pepper
1/2 tsp. cinnamon
1/8 tsp. cloves
Combine all ingredients; bring to full boil. Simmer 20 minutes.
Grilled vegetables are great, you can take a bag of sliced vegetables or make vegetable kabobs and have them ready for grilling. Maybe mix in some shrimp or scallops or chicken breast. They are tasty and quite filling and you get the grilled flavor without the ton of calories of most bbq.
