Check out seasonal cookbooks!
I used to just cook by thinking about whatever I wanted to eat, find a recipe and then go buy the ingredients at the grocery store. Joining the CSA reversed this process for me - the ingredients came to me and then I had to figure out what to do with them! This was initially challenging but I think in the end has actually simplified the process of meal planning for me. Good, seasonal cookbooks have been a great help in this department. Below are some of my favorite seasonal cookbooks that I own and a few that I have been wanting to check out.
