I think Elf is too delicate to be grilled and served on a bun. Maybe a quick sear on both sides and then something in a light lemon cream sauce? Yeah, that'd do it. Garden veg on the side, and cauliflower mash. Pair with a sweet fruity white from the Southern Realms.
Halfling though, that was born to be in a burger. Slightly gamey, nicely marbled, and generally beer marinated. Grind in a little smoked bacon and lightly season. Mmmm. I'd probably go pretzel bun and handcut fries to round it out. Pair this one with a pint of Bruenor's Best Dark Ale (seasonally available).
And for dessert? Candied Brownies.
