When I make a big salad to bring to work for lunch, I put lots of stuff in it! For protein, I add red kidney beans or cannellini beans (usually about half a cup). These beans can really fill you up! I usually dice a zucchini and a yellow squash, plus add lots of grape tomatos. If I have carrots, I will shred some into the salad. Sometimes I throw in leftover vegiies from the night before - steamed broccoli, asparagus, even brussel sprouts! I buy a variety of salad greens - baby spinach, romaine, a package of spring mix with baby lettuces. This all adds up to a very hearty salad. I usually bring a low fat salad dressing or a bit of the balsamic vinagrette that I make myself. I carry the dressing in a tiny rubbermaid container, so that it is not sogging up the salad all morning long.
