Some ideas that came to mind:
- What if we made a pizza pocket but with jam and peanut butter?
- You know how Nutella on toast is one of the easiest things to make? What if we made it even easier?
- You know how people make a cup of tea and forget about it? What if we made a sandwich that worked like this?
Just a silly thought I had when in the shower I wanted to share.
Uncrustables came out shortly after the George Foreman grill.
Someone smashed their PBJ on a Foreman grill and decided to make the result into a product.
Could also be a pie iron thing
Panera released their paninis around the same time too.
