First, I make it myself. If you control your ingredients, you control what you eat. Makes sense.
Second, I use as much whole wheat flour as I can in the crust without getting kickback from the husband and kids. Usually it's about 1:1 wheat:white.
Third, I sneak a layer of pureed vegetables on the crust before I put on the sauce. Not one single time I've done this has anyone been able to tell. I started off doing a little and when no one noticed, I kicked it up to about a quarter to a half a cup per large pizza. I always serve the pizza with fresh cut veggies, but if the kids don't eat them hahahaha they just ate carrots anyway.
Finally, use healthy ingredients. I usually don't put meat on my pizzas unless it's turkey pepperoni or a little ham. I personally don't like lowfat cheese because I find it rubbery, so I use full fat cheese but just less of it. There's nothing saying you shouldn't see the sauce through the pizza, and if you have lots of healthy yummy ingredients on it your family won't miss it a bit!
