Cut the beef into equal cubes and place them in a mixing bowl.
Add the olive oil, garlic, paprika, black pepper, salt, and oregano, then mix until the beef is evenly coated.
Let the beef marinate for at least 1 hour.
Thread the beef, bell pepper, and onion onto skewers.
Preheat the grill to medium-high heat.
Place the skewers on the grill and cook for 8 to 10 minutes, turning regularly, until browned and cooked to your preference.
Remove from the grill and let rest briefly before serving.
Notes & Wine Advice
Notes
Use evenly sized beef cubes for the most consistent cooking. Do not pack the skewers too tightly, because a little space helps the heat circulate better.
Wine Advice
A structured Cabernet Sauvignon works beautifully with the grilled beef, while a spicy Syrah also pairs very well with the smoky barbecue character.
