And, as a matter of fact, perhaps chopped watercress or lettuce (romaine?) or soya sprouts, as a "green veggie" sprinkled with a bit of oil or dipped into something? Boiled beet is another option, one can buy it already boiled. We also take raw mushrooms here with our salads. Anyway, try one thing at a time, and tomato+peppers perhaps peeled to begin with.
