A challenge for you - dinner party menu needed catering to lots of dislikes...

[Yellowflowers]

Having friends over for lunch. Will probably just do two courses - main and dessert.

Between them the guests do not eat the following:

Coriander
Cheese
Offal
Celery
Chicken
Corn
Soy
Rye
Fruit (!!!)
Mushrooms

Any thoughts for nice things to cook? I was thinking a slow cook one pot casserole thing they can help themselves too - perhaps lamb with tomatos and peppers and lots of flabours with nice turkish bread from amazing turkish supermarket near us, followed by some kind of chocolaty dessert.

I would do slow cooked lamb with red wine, garlic, veg, tomatoes like you said with dauphinoise potatoes and green veg - maybe green beans or purple sprouting broccoli, that kind of thing.
Then possibly chocolate bread and butter pudding or chocolate lava pudding (the one with the sauce underneath).
Tummy's rumbling just thinking about it....

Mmmmm sounds excellent idea. And I love chocolate bread and butter pudding so thank you for reminding me of that. Have made it once before.

How do you know they don't like all that?!?
I've never been invited out for dinner and said 'lovely, by the way I don't eat coriander, celery and chicken and everything else beginning with c'
wierd guests IMO

I asked if there's anything they don't eat - that's not all one person though, just a couple of things each!

I never ask people who we have invited for a meal if they don't like to eat anything (allergies are different). Frankly you are being unbelievably kind and patient. To my mind, if you are shouldering the burden of preparing and paying for everything then your guests ought to be sufficiently well-behaved/ grow-up/ decent and eat what is put in front of them.
