Can just suggest the obvious, a selection of roast meats. Since it is a meat feast I can't see a large steak covering the description. Varied is the aim.
Slices of roast beef, lamb, pork, chicken (any other fowl you can get hold of), maybe something more exotic like venison or ostrich or goat. Just wander in and see what your local butcher stocks.
To compliment you might want to consider the many sausages one can get. Possibly fancy ingredient British type ones but also slices of those sausages one finds on the continent. Your local supermarket probably has a wide selection of cold cooked meats.
You could even branch into fish meats, but I suspect that wasn't what he had in mind.
I suspect meat on it's own, the novelty would wear off fairly quickly so had plenty of rice/chips/wedges/whatever as side dishes. And if he has any favourite veg, a few dishes of that too, to add variety to the meal.
Are you sure he didn't ask for a jelly/blancmange/cake feast ?
