Prepare as above, except cut unpeeled apples into bite-size pieces; place in a mixing bowl and toss with lime juice or lemon juice. Add the melon cut into bite size pieces, plus the grapes and the pistachios or the almonds. Fold in the salad dressing. Serve on lettuce leaves. Makes 8 servings.
If you can't find any melon in your grocery store during the winter, you can just substitute another fresh fruit.
