In a large bowl or directly in a zip bag, combine the marinade ingredients.
Add the cubed beef pieces and let them marinate for at least 30 minutes, or overnight. Tip: while the beef marinades, this is a great time to soak your skewers.
Thread the cubes of meat onto the skewers, alternating with vegetables if using.
Notes
Add 1 teaspoon of red pepper flakes to the marinade for more heat.
