This is one of our standbys, especially when vegetables are abundant in the summer months. It freezes quite nicely as well. It’s infinitely adaptable. Many summer vegetables could be used in it (or even left out according to preference)–it’s great for the bumper crops that seem to happen in CSA boxes and gardens.
