i dunno if they charge extra...i've just always done that and i think it's £12 odd a month?
i had cheese and onion "pasty" for lunch...Amy from here (can't remember her user name lol) makes them a lot and she'd told me how to do it the other week.
i cubed and cooked a small potato and an onion in the microwave for 5 mins, when it was mashable, i mashed in my HEa cheese and stuffed it into a ww pitta bread, sprayed it with fry light and put it in the oven.
was nice for a wee change and felt really stodgey...i can see how she feels naughty when she has it with sw chips and beans....and hey, it's the nearest to a cheese and onion pasty we'll get syn free lol x
