This is a bit of an old-school dinner Mum used to make us (and still does on special occasions). It's kind of like a crepe cannelloni. The 'recipe' is pretty loose; make a whole bunch of crepes, fill them with ham, pineapple, cheese and anything else you have lying around. Roll them up and squish them all into a dish, sprinkling with cheese on top. Bake until the cheese is melted and the ham is warm. Serve with a green salad if you want. Enjoy!
