Hot dog sauce recipe from Zimbabwe?!

I am looking for a recipe for a hot dog sauce that a man brought with him from Zimbabwe!. I can not find it any where on the net!. The sauce is like a combination between a sloppy joe sauce and a chili sauce!. It also has big chunks of zucchini and cabbage in it!. The name of the hot dogs here in my town are Z-dogs!. They are very, very good, but messy!.Www@FoodAQ@Com
