I used to eat the small tub of prawn + cucumber pasta salad from Morrisons but it doesn't have any nutritional info on the pack and the staff were clueless when I asked for it.. I would just syn the mayo (probs full fat) use your HE A for the cheese and the ham + pasta should both be free on extra easy. Guessing about 2 or 3 tbsps of mayo - not sure on syns? .. 4 or 5?
