Venison Loin, how to cook?

[NJ Dave]

Someone just dropped me off a venison tender loin/back strap from a deer.
Any recepies on how to cook?
I usually sauteed garlic and onions in butter and deglaze pan with 2 cups of red wine which makes a nice sauce. I then add add some stone ground mustard, salt and pepper, Lil hot pepper flakes. I then thin slice the loin and quick sauteed in the onion mixture.
Loaf of bread to dip and that's it.

Looking for other options.
Thx.
