BBQ Chicken Pizza

I used some of the leftover chicken from Friday on a pizza.  When I have barbecue pizza at restaurants, I always feel like the pizza needs a little something other than just chicken and cheese.  So I added a few things I had to the pizza.   The sweetness of the caramelized onions and the pineapple went great with the barbecue flavor.  I added the carrots to get a little extra veggie boost- the flavor just blended right in to everything else. 

Ingredients
1 pizza crust (try an oatmeal crust- it went great with these toppings!)
1 tsp olive oil
1 small yellow onion, diced
1/2 cup crushed tomatoes from a can
1/2 cup barbecue sauce
2 cups cooked chicken, shredded
1/2 cup shredded carrot
8 oz can crushed pineapple, drained
2 cups shredded mozzarella
1/2 cup shredded cheddar

Preheat oven to 450 degrees.
Heat oil in a skillet over medium heat.  Add onion and cook until caramelized, about 20-30 minutes, stirring occasionally. 
Meanwhile, combine tomatoes and barbecue sauce in a small sauce pan.  Heat over low until warmed through.
Spread sauce and toppings over pizza and cook about 10 minutes, or until cheese is bubbly.
