This was my favorite market in all of Turin. Every Friday the main streets of the historic Moncalieri area were converted to a market. My Italian politics class usually let out about 11 am on Fridays, so I would stop by the apartment and drop off my books, then head out the door to the market (our apartment was only a half block from the main market area). I would buy my produce for the next week - apricots, apples, a few bananas (very expensive in Europe since they are shipped from S. America), fresh tomatoes, lettuce, maybe some stems of asparagus or an eggplant. Then it was on to the cheese stand for some fresh mozzarella and parmesan-reggiano, and a carton of six eggs. Bread I picked up from the local bakery each morning (often a small circle of focaccia pomodoro for lunch, and hard rolls for dinner).
Once I had the produce, I'd make a quick stop by the apartment to put it all away, then it was back to the market. I'd wander through the stalls selling T-shirts, lace, umbrellas, shoes, dresses, luggage, tapes of old American pop stars, even underwear! I'd look for souveniers for my family and friends, a dress to wear to the opera, shoes to wear with my new skirt, etc. I didn't pay more than $20 for anything (including a pair of Italian leather sandals), however purchase could add up fast if you're not careful. There were lots of very cute wrap-around skirts, nice sweaters and great shoes.
If you're in Turin on Friday, catch the #45 bus down Via Massimo D'Azeglio to Moncalieri (get off at the first stop across the bridge over the Po), grab a gelato (a major requirement for any adventure in Italy) at the shop at the bottom of the hill and wander the market for a few hours.
