Steak Marinade

1 tsp. grated lemon peel (I used orange peel and it worked very well)
2/3 cup lemon juice
1/3 cup oil
1 1/2 tsp. salt
1/2 tsp. pepper (I used lemon pepper)
1 tsp. worcestershire sauce
1 tsp. mustard
1 tsp. garlic powder

Mix all ingredients well. Place steak in ziploc bag, add marinade. Marinate for about 6 six hours turning once, half way through.
