Tomatoes are pickled naturally by fermenting in brine. An addictive condiment to have on hand, perfect in everything from sandwiches to salads, or simply enjoyed on their own.
Use mature dill if possible, which has been grown to the point where there are small flowers and longer stalks as compared to the dill typically found in the supermarket. If you cannot find mature dill, you can use a teaspoon of dill seeds in each jar instead. Pickling spice would also work just fine.
