We have a really good lemon steak we make....
Take a top sirloin
score the steak , cut into the top of each side of the meat in a criss cross fashion...
Juice of one lemon, one lime and one orange
Zest from one lemon, one lime and one orange
1/4 cup brown sugar
3/4 cup of soy sauce
Mix the above ingredients together and pour over the steak.
Seal up in a ziplock storage bag, overnight.
When you BBQ, watch the steak, because of the sugar, it will try to burn...
Yum!
