Combine all ingredients and marinate the beef in the refrigerator for at least 30 minutes.
While you wait, if using wooden skewers, soak them in water for at least 30 minutes.
Evenly portion the beef cubes onto each skewer and cook as desired. We would recommend using a cast iron pan over medium heat; allow the skewers to cook for about 2 minutes on each side until a medium cooked meat has been reached. The skewers can also be cooked on an indoor or outdoor grill.
Serve the skewers as is or with lettuce, sliced cucumbers, cilantro and sour cream mixed with the juice of one lime.
