Invited by vegetarians for dinner? Point out that since you`d no doubt be made aware of their special dietary requirements, tell them about yours, and ask for a nice steak.
I've cooked meat for friends, just warned them the inevitable botulism is their problem.
And on the cheese thing, there'seven stealth cheese.. not on the menu, a dish that has no need of it, but there it is.
A friend has a theory that all savoury food is improved with cheese. I disagree.
