Food tour of Italy?

I'm a culinary student right now, and I'm looking for food tours in Italy, I'm not sure which region yet. If anyone has been on one, or knows someone who has I would really appreciate any info/websites. I'm looking for first/second hand info because I'm not sure how reputable a lot of the websites I find are. I'm thinking maybe Tuscany or Sicily, but I'm open to any and all info!! Thanks :)
