I love peanut butter too, with grape jam (never JELLY, Chica!) on soft wheat bread. Cut into triangles, of course!
When Cristina, our exchange student from Madrid, lived with us in high school, she fell deeply and passionately in love with peanut butter. She put it on EVERYTHING--including, memorably, a tuna sandwich.
She also gained about 10 pounds during the summer she lived with us--due, I am sure, to the PB!
I adore Nocilla too--on those little Maria cookies. I used to keep a tube of those and a jar of Nocilla in my residencia in Salamanca--mmmm!!! With the Maria cookies, you don't need a knife, either. Just dip and enjoy!
