How about a small jacket potato with low cal spread with chicken/turkey slices or turkey/chicken breast, prawns and crabsticks. Prawns and Crabsticks are really low cal crabsticks are about 10 cal per stick. You could add some salad in their as well like a bit of red pepper and salad onion for flavour etc. You could also use extra light Mayo and serve it up with a big portion of salad and a bit of black pepper if desired.

You could also maybe roast a red pepper and stuff one with some fillings. A whole roast pepper is like 50 calories for one.

You could also grill a small fish and serve that up with salad.
