So many sandwiches eaten in a lifetime, especially growing up where I had a sandwich for lunch almost every day. While chunky peanut butter and preserves were enjoyed back then, I didn't really eaten as often as I did as an adult. They are just so easy to carry with me. I did it all the time when hiking.
I guess I will say I have eaten more peanut butter and preserve sandwiches than any other, but I wouldn't swear to it.
