Roasted eggplant, zucchini, tomato and onion - great cold - can be served on rye crackers, mixed with pasta, or put in a sandwich or wrap.
Buy little containers and in each one put chopped veggies like carrot, cucumber, celery and serve with a dip - like cottage cheese or low fat sour cream mixed with spices.
Rice salad, if you can find it the french Camargue red rice is gorgeous, mixed with diced peppers, red onion and shrimp or diced meat (dare I say chicken?? LOL)
Smoked salmon bagels aren't too bad, you can get away with a smoked salmon and low fat cream cheese bagel for around 400 calories.
