Lean beef is a wonderful source of protein but so is kangaroo, lamb or goat. All of which would work perfectly with this salad. The yoga approach to meat consumption (we are not all vegetarians) is to eat small amounts of meat compared to our vegetable content on our plates. I eat red meat for iron and it makes me feel good. Of course its your yoga and you must do what is right for your body and philosophy.
Try growing your own bitter greens in the garden or in a pot on the balcony. The fresher you can get your greens the more nutrients they have, and the crunchier the salad.
