"I went to Italy and it was revelation," Grim told me. "I saw local farmers driving up and dropping off vegetables at the pizzerias. I said, Wow. You don't see that in the United States. You see the Sysco truck dropping off cans of stuff. That was such a stark difference. When I got back, I had to have a wood-fired oven in my kitchen. I'd have pizza parties, where I'd invite 50 friends over for pizza, salad, and beer."
