Don’t get me wrong, if you have a good jam or preserves it’s totally fine on a sandwich, and I wouldn’t turn my nose up at it. However, peanut butter doesn’t really need the help, and the extra sweetness from jelly is totally unnecessary. Toasted bread and peanut butter is all you need for a quality simple sandwich.
I strongly disagree. You can’t drop the peanut butter.
But I also agree that you can’t drop the jam.
There are better ways to enjoy plain peanut butter than in bread. Like straight out the jar.
I’d say toast with jelly is definitely a breakfast staple, though.
