In a large skillet over high heat, heat up 1 tbsp of oil.
Once hot, add the steak to the skillet, and season with salt and pepper to taste.
Sear the meat well on all sides, and cook until you reach your desired level of doneness. Because the steak is cut into bite-sized pieces, only a few minutes of cook time is needed to keep from over cooking the steak.
Add 2 tablespoons of butter and 2 cloves of minced garlic into the skillet, and stir to combine and coat the steak bites well.
Serve with freshly chopped parsley for garnish.
