My Dad was a great Italian cook, he came up with these sandwiches from an overload of zucchini and green peppers in his garden. Well every year all of his 5 married children and their husbands and children would take a vacation to a Lake in New Hampshire and rent a huge cottage to stay in on the lake. Well my Dad made a huge batch of these sandwiches and brought them to all of us to have something on the ride up. Would he ever tell us how he made them? No. Finally in his later years he showed me how to make em. They are my favorite now when my garden is full of zucchini & peppers.
