One of the great things about living near farmland is... farmer's markets! Of course it's a little tricky to do here in the heat of the summer, but the Power Road market manages to stay stocked year around with produce that is fresh and for the most part local. It's a small Mom-n-Pop market, but they work with local retailers around the valley to bring in all sorts of different foods that go way beyond produce. They also roast fresh chilies daily, & sell locally made tamales and salsa too.
The prices are what really get me. So many complain about the jacked-up prices of farmer's markets, but this place has always been either the same in price, or I pay even less. Plus, because most of it is local, the food lasts longer!
If you're in the east valley, they are worth checking out and changing where you buy your produce. Buy local whenever you can!
