What don't I put in it!? I treat a ravioli salad pretty much as I would a reg salad. A few add-in ideas for next time:
Asparagus, green beans, brocolli, peas, pea pods, snow peas, roasted squash, , carrots, beets, cannellini beans, garbanzos, sun-dried tomatoes (or any tomato - grape, cherry, roma etc), baby spinach, fresh basil, marinated artichoke hearts, sweet roasted red peppers, black olives, diced red onions, scallions, ham, prosciutto, bacon, pine nuts, mixed greens, lemon/lime/orange zest, cheese(s) of choice. Seafood - shrimp, salmon, tuna.
Think salad, & add ravioli, i.e. Caprese, Greek, Caesar (add croutons).
Here's are a few more ideas:
Ravioli Pasta Salad
Terrific Tortellini Salad
Hazelnut & Chard Ravioli Salad
Or, toast your ravioli - dip in egg & bread crumbs & bake - pile 'em on top of salad.
Have a few more thoughts. Will add on later.
