"Despite being Rome's largest farmers market, the Mercato di Campagna Amica remains down to earth and not at all corporate—as demonstrated by the fact it's only open on weekends. The stalls adhere to the "0 km" philosophy, shorthand for products made or grown within 100 kilometers from the point of sale; and vendors come mostly from Lazio, Rome's home region. It's a crash course in the local leafy greens, amusing in their number and variety, especially to visitors from northern climates. Both the olives and the olive oil you'll find here are worth a splurge, but one of the market's best uses is as a source of super-fresh (and super-cheap) picnic material. Grab some bread, a little fresh pecorino, a few slices of prosciutto, some fruit, and make yourself a lunch." - Katie Parla, Maresa Manara
