Slice your summer squash into bite sized pieces and place in a large bowl.
Add in your thinly sliced onion and all of the fresh herbs.
Drizzle with oil and freshly squeezed lemon juice and zest.
Season lightly to your taste with sea salt & pepper then toss well to combine.
Refrigerate your salad for 1 hour prior to serving to allow the squash to marinate in all the flavors.
Before serving, give it another toss then top with freshly grated parmesan.
Enjoy!
