I would imagine you could make it pretty simply on extra easy and serve it with some veg.
I don't know about quantities but make some mince bolognaise how you like it (I use extra lean mince, mushrooms, onions, red peppers, lean bacon diced, passata and garlic) and then layer in between pasta sheets - for the creamy sauce you could mix fromage frais with laughing cow cheese (your HEX) or just mix with some quark (free) and black pepper and salt. Sprinkle some cheese on top if you want it crispy!
