Third and final vintage sandwich. Yes, more grated apple (I like apples!). I used an own brand of pb which I shall avoid in future as it was insufficiently crunchy.
Sweet Fillings
Peanut butter mixed with an equal amount of jam, honey, syrup or grated apple.
Results

This is as a hearty a sandwich as it looks, although the moisture of the apple means the peanut butter is lighter and less sticky. Would make a decent lunch for refueling during an outdoor pursuit.

I lived on these as a teen vegetarian. I loved them…I will be buying apples when I’m out to relive those heady days! Yum!
