Garden Vegetable Sandwiches....?

Have you ever heard of Garden Vegetable Sandwiches? My grandmother was talking about them yesterday when we were visiting her and she was trying to find the recipe for them. I have never heard of such a sandwich but she says that they are delicious! I guess I should find some time tonight to browse Google to see what I can come up with for her. She is so fascinated by the Internet and the information that can be found so she gave me a list of things to look up for her LOL
