Tomorrow I'm using it on some boneless pork chops.
1/2 cup of low sodium soy sauce
1/4 cup of Worcestershire sauce
2 tablespoons of sugar
2 teaspoons of balsamic vinegar
1/4 cup of canola or olive oil
1 tablespoon of Dijon mustard
Smidge of sesame oil
2-4 garlic cloves, minced
2 scallions, sliced thinly
Freshly ground black pepper
Combine all ingredients in a bowl, whisk, and use it to marinade whatever meat you want to grill. It might also be good on Portabella mushrooms.
