2 tablespoons white wine vinegar

2 tablespoons lemon juice

2 tablespoons dijon mustard

2 garlic cloves -- minced

Place steak in a shallow dish or large heavy-duty resealable plastic bag. Combine remaining ingredients; pour over the meat. Cover or seal and refrigerate overnight. Remove meat; discard marinade.
