Prepare the Grill: For an authentic experience, cook the meat over a charcoal grill. However, a gas grill works well too. Preheat the grill to medium-high heat.
Season the Meat: Rub the meat with chili powder or freshly ground chillies and salt. Ensure it is evenly coated.
Grill the Meat: Place the seasoned meat on the preheated grill. Cook until it reaches your desired level of doneness. For medium-rare, grill for about 4-5 minutes per side.
Rest and Cut: Once cooked, remove the meat from the grill and let it rest for a few minutes. This helps retain the juices. After resting, cut the meat into small bite-sized pieces.
Prepare the Salsa: In a bowl, combine the finely chopped tomatoes, onions, and chili pepper. Add the oil and vinegar, then mix well. Season with salt to taste.
Serve: Sprinkle the salsa over the grilled meat pieces. Optionally, serve with extra chili powder and salt on the side for dipping.
