Place the steak between two pieces of plastic wrap and pound to ¼-inch thickness.
Cut the steak into strips. Season with lemon pepper and salt.
Drip the strips into the buttermilk and dredge in the flour.
Heat 2 tbsp. of the oil on a skillet over medium heat. Add half of the strips and brown on both sides. Drain on paper towels. Repeat with remaining strips.
Serve hot.
Notes
If you have leftover steak fingers, store them in an airtight container in the refrigerator for up to 3-4 days. To reheat, place them in a preheated oven or toaster oven until warmed through and crispy.
You can freeze cooked steak fingers for future use. Allow them to cool completely, then place them in a single layer on a baking sheet and freeze until firm. Once frozen, transfer them to a freezer-safe bag or container and store them for up to 2-3 months. To reheat, bake them in the oven until heated through.
