Make up a big batch of homemade pasta sauce then freeze it in a few single- or double- serving size containers.

I have this same problem with squash and eggplant, as well as the tomatoes.   They grow like weeds until August here.  My neighbors are sick of them.    I've tried everything short of frying.  I was even given a zucchini chocolate cake recipe!  

All we can do is chop up what we don't eat and compost.   Careful with those tomato seeds, though!  Throw one chopped up tomato into the garden and you'll have hundreds of tomato plant "weeds" after the  next rain storm!   Those seeds even survive the digestive system.
