We have leftover beef tenderloin (uncooked) from earlier in the week, and I'd like to use it for an appetizer for New Year's Eve. I have a crostini recipe, but since we're having Cioppino (with aioli and toasts) for the main course, I'd rather something else. The other appetizer is Moroccan crab cakes. Ideas, please! Thanks.
(Oh, and $10 off your order of $50 or more in the Food52 Shop, too.)
