In a bowl or mason jar, combine parsley, red wine vinegar, olive oil, lemon juice, garlic, salt, and pepper. Stir well to blend. Set aside to let the flavors develop.
Salt and pepper, 1 ½ cups fresh parsley, ¼ cup red wine vinegar, 1 cup olive oil, 1 tablespoon lemon juice, 1 tablespoon garlic
In a separate bowl, whisk together olive oil, curry powder, salt, and pepper. Add the beef cubes and toss until well coated. Cover and marinate for at least 30 minutes in the refrigerator.
3 tablespoons olive oil, 1 teaspoon curry powder, Salt and pepper, 1 pound beef sirloin
Thread the marinated beef, red bell pepper, zucchini, and red onion onto skewers, alternating for color and flavor variety.
1 red bell pepper, 1 zucchini, 1 red onion
Preheat your grill to medium-high heat (around 400°F (200°C)).
Place the skewers on the grill and cook for 4–5 minutes per side, or until the beef reaches an internal temperature of 145°F for medium doneness.
Let the kabobs rest for 5 minutes before serving. Drizzle with chimichurri sauce or serve it on the side for dipping.
