2 cloves garlic, minced
1 teaspoon paprika
1 teaspoon ground cumin
1/2 teaspoon cayenne pepper
1 teaspoon dried oregano

Wooden or metal skewers (if using wooden, soak in water for 30 minutes)
For the Chimichurri Sauce:
1 cup fresh parsley, finely chopped
1/2 cup fresh cilantro, finely chopped

2 tablespoons red wine vinegar

Instructions:

Prepare the Beef Skewers:
In a large bowl, mix together the olive oil, minced garlic, paprika, ground cumin, cayenne pepper, dried oregano, salt, and pepper.
Add the beef cubes to the marinade, tossing to coat well. Cover and refrigerate for at least 30 minutes, preferably 1-2 hours.
Make the Chimichurri Sauce:
In a medium bowl, combine the chopped parsley, cilantro, minced garlic, olive oil, red wine vinegar, lemon juice, dried oregano, red pepper flakes, salt, and pepper.
Mix well and let the flavors meld for at least 15 minutes before serving. Refrigerate until ready to use.
Cook the Beef Skewers:
Preheat the grill to medium-high heat. Thread the marinated beef cubes onto the skewers.
Grill the skewers for about 2-3 minutes per side, or until the beef is cooked to your desired doneness.
Remove from the grill and let rest for a few minutes.
Serve:
Arrange the beef skewers on a platter.
Drizzle some chimichurri sauce over the skewers and serve the remaining sauce on the side.
Notes:
Serve with a side of grilled vegetables or a fresh salad for a complete meal.
Adjust the spiciness by increasing or decreasing the cayenne pepper and red pepper flakes.
This dish can also be made with chicken or lamb for variation.
