Cheese and gherkin rocks! My DDs are both die-hard gherkin lovers (I sometimes catch DD1 snacking on them with a fork straight out of the jar)!

Another one from my childhood - cheese vegemite and celery...you slice the celery into thin c-shapes, trust me is the most underrated sandwich vegetable, it has a perfect crunchy texture. Also works with: peanut butter and celery, cream cheese spread and celery...mmmmmm.

And latest discovery - ham avocado and alfalfa sprouts. It just works.
