I am NOT a fan of BBQ anything, however I can say every time I've had a pizza that has BBQ sauce, I hate to say but it really does compliment VERY well. I won't order it but I absolutely would destroy it if I got one on accident or someone else supplied it.
Not a fan of BBQ sauce on pizza either, but one night we had a pizza that the customer never picked up. It was BBQ sauce with pepperoni and I believe ground beef on it. Yea, don't ask. Anyway, we're not about to let it go to waste. So we all partake. Gotta say, I actually really liked it. The sweetness of the BBQ sauce complimented the flavoring from the pepperoni. And it was greasy as fuck.
Back when I was in the US you used to be able to buy California Pizza Kitchen pizzas in the frozen section. I think they have since changed the recipe/crust/size. There was a chicken one with garlic and onions that was really good but after a while I couldn’t find them anymore.
