It was absolutely lovely! So many of the production team are going home to make more tonight!
If you'd like to make some - here's the recipe: Take a large tin of tinned spaghetti, line a casserole dish with it. Then make mashed potato - mixing in some grated cheese into it. Cover the spaghetti with cheesey mash, then grate extra cheese over it and add some salt and pepper. Bung in oven for half an hour until top is golden.
