We decided not to do pizza every Friday. See, if my family ate anything but cheese on their pizza, it would help. But they don't... and I don't think anyone needs a day where they eat nothing but cheese and refined flour for a full meal each week. lol... I on the other hand, am the one who piles on the veggies. I even put boccoli on my pizza sometimes when it is fresh from the farm. I thought for a while that the kids would follow my example and try new things each week with their pizzas... but alas, four months of pizza Friday and we were still doing cheese pizzas with occasional olives. So we have moved it to a monthly thing... or whenever we get a hankering for a comfort food in front of a Netflix. ;)
I did make pizza night a bit more fun however. I bought mini pizza pans from a local kitchen store and each person now gets to make their own mini pizza. It's pretty cool... esp for the two older kiddos that get to do the whole process of kneading out the dough and getting it on the pan before baking. They loved it!
