Step 1

In a small bowl, whisk together all ingredients for marinade.

Step 2

Cut steak into pieces and add to a large resealable bag.

Step 3

Pour marinade over steak, seal bag and place in refrigerator to chill for at least 30 minutes or up to 4 hours.

Step 4

Toss the vegetables with the oil and season them with garlic powder, salt and pepper.

Step 5

Remove steak from bag and discard marinade.

Step 6

Thread steak and vegetables onto skewers.

Heat a grill over medium high heat (approximately 425 degrees F).  Clean the grill grates and rub them with oil to keep the kabobs from sticking to the grates.

Step 8

Place kabobs onto a hot grill and cook for approximately 8-9 minutes, rotating the kabobs every 2-3 minutes, until the steak reaches an internal temperature for 140-145 degrees F.

Step 9

Remove from grill and serve immediately
