Instructions

1. To a medium bowl add, olive oil, tamari sauce, worcestershire sauce, dijon mustard, fresh lemon juice, dry oregano, dry rosemary and pepper. Using a whisk, mix everything together.
2. Add meat to a large bowl or ziplock bag. Pour half of the marinade over the meat and toss to coat. Reserve remaining marinade.
3. Let meat marinade for 30 minutes to 1 hour.
4. In the meantime, add potatoes in microwave safe container with 1/2 cup of water. Cover and cook on HIGH for 7 minutes to slightly cook potatoes. (should be able to pierce with a fork or knife)
5. Assemble kabobs: alternate red pepper, green pepper, red onion, meat, yukon potatoes and mushrooms. Repeat. (I try to get 3-4 pieces of meat per skewer) Continue process until ingredients are gone.
6. Heat grill to medium high heat, about 375-400 degrees F.
7. Make sure that grill grates are clean. Spray grill grates with cooking spray or rub down with an olive oil soaked rag.
8. Place steak kabobs directly on the grill. Grill each side for 3-4 minutes, you want a nice char. Basting the kabobs with remaining marinade while grilling. Remove the kabobs from grill and let rest for 5 minutes.
9. Serve.
