1-First Step: Prep the Steak and Marinade Cut 1 lb ribeye steak into 16 equal pieces, about 1-inch cubes. Pat dry with paper towels. Whoa, uniform size means even grilling, no tough bits. Place steak pieces and 8 baby bella mushrooms in a gallon-sized zip-top bag. Now whisk marinade: 1/4 cup soy sauce, 1/4 cup barbecue sauce, 1/4 cup vegetable oil, 2 Tbsp white vinegar, 2 Tbsp Worcestershire sauce, 1/2 tsp garlic powder. Pour over steak and mushrooms. Seal bag, squish to coat. Marinate in fridge 30 minutes to 2 hours. Don't skip this. It locks in juices. Back home, I marinate while prepping sides.

2-Second Step: Parboil the Potatoes Grab 8 baby Yukon Gold potatoes. Boil in salted water until fork-tender, 5-7 minutes. Drain, rinse under cool water. This step is key. Potatoes cook fast on grill without burning steak. Let cool 10 minutes. Pro move: skins stay on for texture. In small-town summers, we parboil in big pots over open fires sometimes!

3-Third Step: Assemble the Skewers Heat grill to medium-high, about 400-450°F. Oil grates well to prevent sticking. Thread skewers: start with steak, then potato, steak, mushroom. Repeat pattern twice per skewer. So per kabob: steak, potato, steak, mushroom, steak, potato, steak, mushroom. Makes 4 kabobs total. Leave small gaps for heat flow. Metal skewers best, but soak wood 30 min if using. Fun part, kids help here!

4-Fourth Step: Grill to Perfection Place kabobs on grill. Cook 5-6 minutes per side, total 10-12 minutes. Flip every 3 minutes for even char. Brush with extra marinade midway if you saved some. Pull steak at 135°F for medium-rare. Rest 5 minutes tented with foil. Smoky, caramelized edges, juicy inside. Wow, neighbors smell it from blocks away!

5-Final Step: Serve and Enjoy Slide off skewers or serve on. Pair with greens, rice. Feeds family fast. Leftovers? Rare here! Nutrition per serving keeps it wholesome. Oven option: 350°F, 30 minutes, rotate every 10. Adjust sweetness in marinade if you like less BBQ tang. There you go, perfect Grilled Steak And Potato Kabobs.
