2 pounds (1½-inch-thick) ribeye steaks, cut into 1-inch pieces
1 (8-ounce) package fresh cremini mushrooms
8 (6- to 7-inch) wooden skewers, soaked in water for 30 minutes
Salt and ground black pepper, to taste
2 large tomatoes, chopped
2 tablespoons white balsamic vinegar
2 tablespoons olive oil
2 teaspoons chopped fresh rosemary
1 teaspoon kosher salt
1 clove garlic, chopped
Garnish: fresh rosemary
Instructions
For kabobs: Bring a large stockpot of salted water to a boil over medium-high heat. Add potatoes; cook until tender, about 20 minutes. Drain potatoes, and cut in half.
In a medium bowl, whisk together oil, lemon juice, vinegar, garlic, salt, and mustard. Divide mixture between 2 medium bowls. Add steak to first bowl, tossing to coat. Place potatoes in second bowl, tossing to coat. Cover and refrigerate for
minutes, turning once.
Remove beef and potatoes from bowls; discard marinade. Thread beef, potatoes, and mushrooms onto skewers. Sprinkle kabobs with desired amount of salt and pepper.
Preheat a cast-iron grill pan over medium-high heat. Place 4 kabobs on pan, and cover loosely with foil. Cook, turning occasionally, until steak reaches desired degree of doneness, about 3 minutes for medium-rare. Repeat with remaining kabobs.
For balsamic tomatoes: In a medium bowl, stir together tomatoes, vinegar, oil, rosemary, salt, and garlic. Serve with kabobs. Garnish with rosemary, if desired.
