The Phoenix Roadrunner Park Farmers Market is a great little market to find all kinds of produce and local products. The venders are generally about 40% produce, 30% local food products, 15% percent fresh food/drinks, and 15% miscellaneous products.  If you're only looking for produce, it can be difficult to remain disciplined with so many other great local food products, just watch your budget!  I recommend avoiding the parking lot adjacent to the market, it is better to park of 36th Street and take a little stroll through the park. Some of my favorite products here are fresh chili peppers, fresh herbs, unique fruits/vegetables, local dairy products and tamales.
