Ingredients

Scale

Steak Marinade

½ cup balsamic vinegar
2 tablespoons honey
1 tablespoon whole grain mustard
3 cloves garlic, minced
Salt, to taste
Pepper, to taste
14 ounces sirloin, cut into 1-inch cubes

Tomato Marinade

2 cups whole grape tomatoes
⅓ cup olive oil
2 tablespoons fresh rosemary, stems removed and chopped

Other

1 ½ pounds baby potatoes
6 metal or wooden skewers

Instructions

Preheat Grill and Soak Skewers. Preheat your grill to medium heat. If using wooden skewers, soak them in water to prevent burning during grilling.
Prepare Steak Marinade. In a large bowl, whisk together balsamic vinegar, honey, whole grain mustard, and minced garlic. Season the mixture with salt and pepper according to your taste.
Marinate the Steak. Add the cubed sirloin steak to the marinade and toss well to coat all pieces evenly. Cover the bowl and refrigerate for at least 20 minutes, or up to overnight for deeper flavor.
Prepare Tomato Marinade. In a separate bowl, combine whole grape tomatoes with olive oil and chopped fresh rosemary. Set this mixture aside so the flavors meld.
Parboil the Potatoes. Place baby potatoes in a large pan and cover them with water by about an inch. Bring to a boil and cook for 8-10 minutes until the potatoes are just barely tender when pierced with a fork. Drain and set aside—potatoes will finish cooking on the grill.
Assemble the Kebabs. Thread the skewers in the following pattern: start with a potato, followed by a piece of marinated steak, then a grape tomato. Repeat this sequence two more times and finish with a potato on each skewer.
Grill the Kebabs. Lightly oil the grill grates to prevent sticking. Place assembled kebabs on the grill and cook for about 5 minutes per side, totaling approximately 10 minutes. This ensures the steak cooks without overcooking and the potatoes and tomatoes get nicely charred.

Notes

Soaking wooden skewers helps prevent them from burning on the grill.
Marinate steak cubes longer for enhanced flavor; overnight is ideal.
Parboiling potatoes ensures they cook through on the grill without burning outside.
Adjust grilling time based on steak thickness and grill heat to avoid overcooking.
Use metal skewers if preferred, which do not require soaking.
Serve with a side salad or dipping sauces for a complete meal.
