I eat lots of salad and veg, and like the others have said, I suggest you avoid the basic lettuce and cue.
Try mixing grated carrot, thinly slice red onion and tomato with a little balsamic vinegar. Serve on heaps of rocket with some feta cheese, chopped apple and radish.
Go for the three colour rule. If a salad has at least three colours it will be tastier! Green, red and yellow for example, lambs lettuce, yellow pepper, red radish or beetroot. Green, orange and white, baby leaf spinach with grated carrot, orange pepper and celery. And try basil, its dreamy. Add some of the low fat low sugar salad dressings to help flavour your salads and keep experimenting.
