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.
Jelly is for children.
Use jam instead. Organic (no HFCS) strawberry is my go-to.
Or preserves. I prefer strawberry with peanutbutter myself, but if I’m just spreading preserves or jam on a pastry, I like peach.
