I just got my tomatoes in the ground last week, and I can't wait to get some on a pizza. We always had a big garden when I was growing up, so I'm familiar with the perfection of home-grown tomatoes, but I've never tried to make a pizza sauce. I'll be snooping around for recipies in the next few weeks as my "pizza fruits" mature.
I can't think of anything else I could grow: olives, mushrooms? I hadn't though about herbs but I guess I could try that. We do get some organic straight-off-the-pig, never-processed-in-a-factory sausage and bacon from time to time. And that is, of course, at least 10 times as good as anything you get at the super market.
