This is, of course, a very narrow comment, but it seems to me that vegan salads based on boiled rice (for bulk) are pretty versatile. Add a cut apple, fresh herbs (dill, young garden marigold, garden nasturtium, parsley, rocket, basil in moderation), oil, spices, perhaps some other fruits if you like them, boiled asparagus, tomatoes... I like it also because the rice can be stored in the fridge, and the rest doesn't take much time to add. I hope it is of some use to you:)
