Thank you for all the suggestions on what to do with the bounty of crookneck squash. Tonight for dinner I combined it with red onions, green beans, chicken broth, then finished it with a little balsamic vinegar and basil. It was delicious.
I've made cherry clafoutis and peach clafoutis, but never blueberry clafoutis. That changed tonight. Blueberries are one of my favorite fruits. Combined with a light eggy batter and sprinkled with cinnamon sugar - delectable.
