In a saucepan combine tomatoes, pineapple, brown sugar, vinegar, Worcestershire, paprika, onion, garlic and mustard powder. Stir together and bring to a boil. Reduce heat and simmer for about 20 min. Pour sauce in a blender or food processor and process until smooth. Allow to fully cool in refrigerator.To Make Pinwheels:
Pre-heat oven to temperature that pizza dough packaging calls for. Flour counter surface and slightly roll out pizza crust to a nice rectangle. Make sure BBQ sauce is cooled and spoon about a cup onto crust. Spread out evenly, leaving edges clear. Top with mozzarella (may not need it all), ham, then red onion. Lengthwise, roll up pizza rolls tightly. Make 1 in slices and place on greased baking sheet. Bake in oven 10-15 min or until golden and fully cooked. Remove from oven and top with chopped cilantro.
