I've always bought sun-dried tomatoes in oil, but about a month ago, I bought a little container of them, and they're not packed in anything. They're awfully chewy and leathery. Do I just chop them up very fine anytime I want to use them? Or can I do something to them that makes them easier to eat? Boil them? Put them in a jar with some oil? I bought them wanting to make great mayonnaise-cucumber-tomato-salt-and-pepper sandwiches, but it's weird to have to gnaw at one of the ingredients in my sandwich. I'll do it if I have to, but ... do I have to? Thanks everyone!
