Ingredients

• 16-20 oz. Top Sirloin, Tri-Tip Steak, or Petite Sirloin
• 8 oz mushrooms, washed and air-dried (Crimini)

• 2 tsp. Bragg’s liquid aminos
• 1 tsp. garlic powder

1. Trim the meat well and cut steak into pieces about 1 1/2 inches square.
2. Whisk together the olive oil (PHASE 2) , white wine vinegar, Worcestershire sauce, garlic powder, all purpose seasoning salt (preferably Vege-Sal),  and lots of fresh ground black pepper to make the marinade.
3. Put steak pieces into large Ziploc bag, pour in the marinade mixture, and marinate in refrigerator 1 hour.
