Lemon Barbecued Chuck Steak

Another favorite from Mom's arsenal. :)

1 chuck steak (1 1/2" thick)
1 tsp grated lemon peel
2/3 c lemon juice
1/3 c salad oil
1 1/2 tsp salt
1/8 tsp pepper
1 tsp Worcestershire sauce
1 tsp prepared mustard
2 green onion tops, chopped

Score fat edges of meat. Place in shallow dish. Combine ingredients and pour over steak. Let stand three hours at room temperature, turning steak several times.

Cook over hot coals, about 12 minutes each side. Brushing occasionally with marinade. Cut across grain before serving.
