Pizza Party Rage
I'm sure it would shock people to hear anyone speak out against the ubiquitous and much beloved pizza party. After all, everyone loves pizza (well, my grandmother claimed not to, but I always suspected she said that to be contrary!) it can be cheap, and doesn't require utensils.
But anyone who lives with food intolerances knows that sometimes pizza is no party. Two of the most common reactive foods are dairy and wheat... the two most important ingredients in a standard pizza. Ordering in pizza for a party can be fraught for many other reasons- it may contain soy (another top reactive food); it may not be suitable for people who keep kosher or halal, and it sure to be unsuitable for vegans. I have several friends with allergies to nitrites and nitrates, which are in almost all the cured meats on delivery pizza.
Even if none of these are an issue, good pizza isn't cheap. People who like their food to actually be tasty may not enjoy delivery even if they don't have food issues.
Of course, if you know everyone at your party is fine with the pizza you plan to order, go for it. If you aren't sure, or if you KNOW people with food issues will be coming, please give it a second thought. I can't tell you how many times I have opted out of a social event because I knew pizza ( or lasagna, or another thing I can't eat) was going to be the main course. I know I'm not the only person who has done this. I can always bring my own food, but truth be told, unless it's a potluck anyway, that kind of sucks. Pizza could be an option among many (I have some hints about feeding a wider range of people here )or, if you know one or two people with dairy or wheat issues will be at your pizza party, you could ask them what frozen pizza they CAN eat and offer to provide it to them ( at no extra cost, if there is a buy in) .
Better yet, plan an event around a salad or deli bar, where everyone can compile their own plate and make sure everything on it fits their needs.
