Try Bibb lettuce with living roots in a clamshell container. Might be called Boston or Butter lettuce. Easy to clean the leaves and just enough for 2 salads. Also great for lettuce wraps. Iceburg has a lot of bitter parts I discard anyway. I'll pick up a Mediterranean salad and find it's good for a second day~ generally a mix of spring greens, baby spinach, artichoke hearts, olives, chickpeas and shredded carrots. Already done~ no work no waste. I'm not a fan of cooked vegetables but often make a platter of sliced red peppers, cucumbers, zucchini, radish and red pepper hummus. Campari tomatoes with homemade vinaigrette is good too.
