Perhaps you could honour those who have given them to him,
and ask for their best suggestion on how to cook!
I've never cooked elk meat, but yes, for venison and moose meat.
For those, I never really did anything different with them, than with similar beef cuts.
Stove top, oven, and BBQ.
Like IceBlossom, I would suggest the oil marinade.
Though for me it would be more likely an oil/seasoning/spice rub
while it sits on the counter before I cook.
