In my menu planning article I mentioned that one of my goals when planning my family meals was to use in season and locally grown food when possible. The first question I am asked about this is “How do you know what is in season?”. Portland, Oregon has a Department of Sustainable Development and part of their mission is to promote Sustainable Food. If you do a google search for “in season produce” + “your state” or “your city” you (hopefully) will find something similar.
Some websites you might want to look at (I am not vouching for the content on these sites, but they look interesting and topical, if you know a good site please shoot me a link):
