I think this pizza should be quite healthy... I always get my chicken breast fresh from the market and dice it in a food processor. All the rest of the ingredients I get from the market as well. I guess the only unhealthy part is the base and the BBQ sauce... I haven't worked out how to make that myself yet, plus it sounds like too much hard work
Once you finish cooking it, it can get quite juicy... so I usually let it sit for about 10 minutes before eating it
