If that's your definition of junk food, then so is half of the stuff you can order in regular, expensive restaurants.

It's possible to make very healthy pizza but the big chains make it pumped full of oil, sugar and meat.

Again, if your definition of "unhealthy" contains "meat", then half+ of the regular food is out.

Also, "healthy" pizzas and tasty pizzas as sets have little to no intersection. Which is fine for food you don't eat day in, day out.
