Step 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.

Step 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.

Step 3

Let meat marinade for 30 minutes to 1 hour.

Step 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)

Step 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.

Step 6

Heat grill to medium high heat, about 375-400 degrees F.

Step 7

Make sure that grill grates are clean. Spray grill grates with cooking spray or rub down with an olive oil soaked rag.

Step 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.

Step 9

Serve.
