When we have the whole extended family at the lake each July, we each take a night to provide dinner, because otherwise trying to coordinate dinner for 25 people every evening is too arduous. This year my sister-in-law did a make-your-own-pizza dinner and it was so genius that I blatantly stole the idea and had one of my own over the weekend.
It's so easy, and great for groups. Here's how I did it:
After rolling out a big 'ole sheet of butcher paper onto my kitchen island, I plunked all the ingredients right on top and wrote the instructions on the paper. (I actually used painters paper from Home Depot because that's what I had in the garage.) This meant that we dirtied almost zero dishes and the clean up was a cinch!
We grilled the pizzas instead of baking them, saving tons of time and mess. And the taste was the same as pizza dough! Better, even. I bought three kinds of naan from Whole Foods (original, garlic, and wheat).
