Have you tried stir fry? Bok choi, pak choi, tatsoi, and other Oriental veg is great (throw in some of that broccoli for a different taste). Baby chard is great in stirfries as well as salads, as is kale and other leafy greens. Have you tried different combinations for salads for variety? Something like purslane, lambs lettuce, watercress, fresh parsley and coriander/cilantro, the red lettuce types... or a new combination with toppings: avocado, alfalfa sprouts, and a spinkling of sunflower seeds for example, or if you are able to have some fruit carbs, sectioned grapefriut (without the white membrane) is good.

Hope this helps!
