Beef & Mixed Mushroom Skewers

Tastes like grilled, but done in the oven?  Yes, it is possible!  These skewers are done under the broiler and pretty easy.  Just takes time to assemble them, that's all.  I modified the recipe slightly and did one step differently, but doubt it made much difference.  Will make these again for sure!

Ingredients:

11 oz. fingerling potatoes, cut in 1 inch pieces
2 T. balsamic vinegar
5 T. olive oil
2 T. chopped fresh oregano
2 tsp. chopped fresh thyme
2 tsp. McCormick Montreal steak seasoning, plus a little more for sprinkling
1 lb. mixture of cremini and button mushrooms, stems removed
12 oz. boneless ribeye steak, cut into small cubes

Instructions:

1. Place potatoes in a medium saucepan and cover with lightly salted water.  Bring to boil and simmer for 15-20 minutes or until fork-tender.  Drain and set aside.

2. In a small bowl, whisk together vinegar, olive oil, oregano, thyme, and steak seasoning.  Set aside.

3. Heat broiler to HI.  Spray a large broiler pan with non-stick spray.

4. Thread potatoes, mushrooms, and meat cubes on 8 metal skewers (or bamboo skewers that have been soaked for 20 minutes).  Place on prepared broiler pan.

5. Brush generously with half of the vinegar mixture on one side, then sprinkle with a little additional steak seasoning all over.

6. Turn skewers over (easiest to do end-to-end, I discovered) and brush remaining mixture on other side.  Sprinkle with a little additional steak seasoning all over and place in oven (rack in middle).

7.  Broil on one side for 5 minutes, then turn skewers over and broil on other side for 5 minutes.

8. Plate it up and enjoy!  (I served them with corn-on-the-cob, but they would be great on their own, too (and plenty filling)).
