I probably ate a salad a day while I was touring in France. I always ate a baguette along with the salad for added carbs.
The salad always had red bell peppers, celery (can buy by the stock in France), carrots, cucumber, feta (or some local) cheese, tomatoes, red onions and olives.
Depending on what I could find in the local market, I would add avocado, snow peas, various kinds of nuts (usually walnuts) or seeds (raw sunflower seeds are my favorite), a crunchy apple, or anything else that looked good.
I never found any baked tofu in France but in places where that was available, I would definitely add that, too.
For dressing, I carried olive oil and Balsamic vinegar.
The things I didn't consume at one sitting, I would carry and then buy everything else, find a bench and start chopping. I popped everything into my big cooking pot and started eating.
Salads are one of my all-time favorite foods but it didn't seem to me that they supply lots of energy. But, I am always hungry on a bike tour anyway so it is hard to judge by me.
