This is a wonderful summer dish to make to use your fresh tomatoes and zucchini from your garden. I have made this dish in the winter and used canned tomatoes and it was just as good.

Surprisingly delicious. I made it for a pot luck b/c it was the ingredients I had. I did not expect to love it, but I did. I also had kohlrabi and rice so I added those. I used mozzarella instead of parmesan, still great.

This made a nice part of dinner tonight! I used part zucchini and part yellow squash. Great to use up garden abundance. Thanks!
