Is it something like this?

4 cups carrots, sliced, cooked in salt water until tender crisp.
1 medium onion, thinly sliced in rings.
I green bell pepper, thinly sliced in strips.

Marinade:
1/2 cup oil
1 cup sugar
3/4 cup vinegar
1 can condensed tomato soup
1 tsp. dry mustard
1 tsp. Worchestershire
1/2 tsp. salt
1/4 tsp. pepper

Cover vegetables with marinade and chill overnight. Keeps a long time.

I can vouch for the recipe, I make it regularly. I'm not aware of any special connection to the BVI. My family has been making this for years in the Midwest.
