Island Teriyaki

My mom has been making this since I was a teenager. It is SO GOOD!! and SUPER EASY!
It is also inexpensive. I did both chicken and steak for dinner tonight. I usually serve it with fried rice.

1/2 cup soy sauce
1/4 cup vegetable oil
2 TBLS. molasses
2 Tsp. ground ginger
3/4 tsp. instant meat tenderizer
2 tsp. dry mustard
6 cloves garlic
1 1/2 lbs round steak
Mix above ingredients I marinate this 4 hours or more. You slice the steak thin across the grain and put on skewer sticks. Then grill on barbecue, broil in oven
