Would panko work for the coarse breadcrumbs? I have regular and whole wheat versions.

Thanks June, Pegeen, and Monita -- I appreciate you weighing in. And I agree, panko is fine!

I was about to say the same thing, Pegeen. This is such a delicious way to use the bounty of summer squash. And the Salsa Verde is so good for many additional uses. Panko is a handy item to have on hand for quick toppings.

Panko works fine - that's what I used and the dish was delicious. I'd recommend regular Panko instead of whole wheat for flavor reasons.

I think Panko would be fine. I often sub panko for bread crumbs
