Grilled Chicken Marinade

3 T oil (I use a mix of canola & EVOO)
1T + 1.5t soy sauce
1T red wine vinegar
garlic (I usually zest 2-3 cloves)
salt & pepper

This marinade is for 2 -3 servings; that's why the measurements are kind of weird.  I like to measure things most of the time, but I'm getting better about "eyeballing" it.  =)

Just combine all the ingredients and soak your chicken breast in it for a few hours - (and obviously, grill) yummo! 
Also - the original recipe calls for 1 T worcestershire sauce & 3/4 t dry mustard, but we didn't have either of those on hand, so I omitted them and added the garlic myself because we love garlic and always have it on hand!
