Ingredients
- 3/4 cup balsamic vinegar
- 1/3 cup extra virgin olive oil
- 3 tablespoons Dijon mustard
- 5 garlic cloves, minced
- 1 teaspoon salt
- 1 teaspoon pepper
- 1/4 teaspoon crushed red pepper flakes
- 2 tablespoons chopped fresh rosemary
- 2 to 3 pounds sirloin roast, cut into 1-inch cubes
- 1 red onion, cut into squares (optional)
Instructions
- In a small bowl, whisk together the vinegar, oil, mustard, garlic, salt, pepper, and red pepper flakes. Measure out 1/3 cup of the mixture and set aside for basting later.
- Add the rosemary to the bulk portion of the marinade. Pour it into a large resealable bag and add the meat. Press out extra air, seal, and refrigerate for 4 to 8 hours.
- Preheat grill on medium heat.
- If using wooden skewers, soak them in cool water for 20 minutes. If using red onion, start with red onion on each skewer, then fill most of the skewer with meat, and finish it off with red onion.
- Whisk the reserved basting sauce to recombine. Grill the kebabs, turning every 2 minutes or so and basting with the sauce, for about 10-12 minutes.
- Transfer kebabs to a plate, tent with foil and let rest for 5 minutes. Serve.
