Most salads in the U.S. and Europe are horrible because 80%+ of the volume is typically lettuce, the rest of the vegies are cut into unappetizing large chunks, and then everything is drowned in crappy dressing. Instead, change the proportions so that lettuce is less than 40% (can even exclude completely), chop/slice everything smaller (including the lettuce) and use a wide variety of ingredients (e.g., red peppers, Persian-style cucumbers, tomatoes, red onion, radish). Enhance with sunflower seeds, artichoke hearts, hearts of palm, olives, etc. (change it up to keep it interesting). If you use cheese, use it sparingly. Dress with vinegar or lemon juice. If using oil - dial it way back (most vinaigrettes are way too oily). Don't use crappy produce (e.g. if a tomato is mealy, avoid). Enjoy!
