Boy, these all sound good.
I decided to make a tomato, zucchini, and onion salad. Just dice them all in smaller pieces and add a vinegarette dressing. And some basil if desired. Also can add walnuts or even a package of the glazed walnuts. I just am tired of making the same things for picnic. I just tried this recipe the other day at a friends. I loved it. I guess it is best if the dressing is one it for at least an hour before serving.
Thanks for your suggestions.
