Farmers markets are not always less expensive than supermarkets. But you have higher-quality produce and, within the range of what's in season, often you have lots of choice. Tomato season brings on heirloom and hybrids, tiny and huge, yellow-striped and orange tomatoes. Buying from these markets helps put dinner on the table quickly because fresh produce often needs very little preparation. Tomatoes, for instance, need just to be washed, cored and sliced.
Corn needs boiling water.
Peaches and strawberries and goat cheese can be eaten without further ado. You need to shop with seasonal expectations. In this area, it'll be difficult to find corn before mid-July. Lettuce appears only in spring and fall. Green beans and summer squash are available in mid-June.
