Gosh, what did I start with that thread? 
I shall have to call up SIL and beg for her recipes!
A lot of what she eats is just nice ways of cooking vegetables in different oils and herbs etc, makes them more interesting I guess. Nice cheeses, but just small portions.
She does mushrooms, just fried in a little bit of Garlic Olive Oil with parsley, I've had them a couple of times when she's cooked and they are delicious, feel like a real treat.
