Steak Bites (adapted from here)

½ cup soy sauce

½ cup olive oil

juice of one lemon

¼ cup Worcestershire sauce

2 cloves garlic, roughly chopped

1 tablespoon dried Italian seasoning (basil, rosemary, thyme, etc)

1 teaspoon black pepper

1½ pounds top sirloin steak, cut into one inch cubes

In a large ziploc bag, combine soy sauce, olive oil, lemon juice, Worcestershire sauce, garlic, Italian seasoning, and pepper.  Slosh it around to combine.  Add beef and marinate in the refrigerator for 3 hours to overnight.  
Heat a large skillet over high heat.  Add steak pieces one by one (don’t just dump it all out or there will be too much liquid).  Discard remaining marinade.  Cook over medium heat for about 3-5 minutes.  Serve with mashed potatoes or rice.
