Try a SW Quiche... My favourite is the one that turns out like a cheesey pasta dish. I get the Mild Cheese & Broccoli Pasta n Sauce, make it up according to the package directions. Then add a small tub of cottage cheese, stir it all up, then add 2-3 beaten eggs. Pour it into a dish and bake it, around Gas 4, for about 45 minutes until it's nearly all set, then put some grated cheddar on top and bake til the cheese is melted and golden and the "quiche" is set in the middle.
I use 2oz of cheese and then I know if I eat half of it (which is a LOT, I don't always manage it!) then I count the cheese as my HexA. It's very yummy, and super easy!
