Prepare the meat slices ensuring they are very thin.

Lightly coat the meat slices in flour, shaking off any excess.

Melt butter in a skillet over medium-high heat.

Quickly cook the meat slices in the melted butter, turning once to cook evenly.

Remove the cooked meat from the skillet and keep warm.

Pour lemon juice into the skillet to deglaze, adding a little water if needed.

Add grated lemon rind to the sauce.

Return the meat to the skillet and turn to coat with the sauce.

Serve immediately with your favorite vegetables.
