This is a big hit with the kids as its easy to make and involves very little work. It can be made with or without mushrooms depending on your taste. My mum made it up when i was a kid and I cook it for mine now.
Used different ingredients. I added 1/2 red onion, some leek, peas and parmesan cheese to give it more flavour. - 04 Nov 2009
Altered ingredient amounts. Preferred to use 1 Tablespoon of lemon rather than 2 when I make in future - 06 Aug 2009
Used different ingredients. Instead of cream cheese or yogurt I used to use Campbell's double concentrate mushroom soup to mix with the tuna and pasta. I would then squeeze lemon on top with cut slices of lemon around the sides of a casserole dish and bake in the over for a crunchy top. I survived being a student in the 80's on this. - 04 Aug 2010
