Soulasphyxi saidAnd what would that salad contain?
A tall order. You might as well ask what would the world's best dish contain.
But for me, a good salad includes a variety of tasty greens, including arugula, and avocado slices, hearts of palm, and artichoke hearts. (There was a restaurant in San Antonio, Texas that used to serve all 3 of those last items in one of their salads -- YUM!) Some cherry tomatoes, usually no onion or cucumber for me (indigestion issues), perhaps some shredded cheddar cheese.
If I want protein then crumbled or sliced hard-boiled egg, or chicken or diced ham, perhaps prosciutto shreds, maybe some small shrimp, even a bit of anchovy. I leave out croutons, just not to my taste. For dressing I stick with simple vinegar and olive oil for health reasons, and I really do like the taste. Lately just wine vinegar, not balsamic, gotten kinda tired of it.
I've had much more exotic salads, but my tastes are actually rather simple.
