In a small saucepan over medium-high heat, combine the soy sauce, monk fruit, ginger, garlic, vinegar and xanthan gum. Bring to a simmer, stirring until the monk fruit has dissolved and cook until the sauce has reduced by half, about 5 minutes. Let cool to room temperature.
Preheat the oven’s broiler and oil a rimmed baking sheet with 1 tablespoon avocado oil.
Season the flank steak with salt and pepper and place onto the baking sheet, rubbing the second tablespoon of oil all over the surface. Broil on high for 8-10 minutes, for medium rare (125ºF), or until cooked to your liking. Let the steak rest for 10 minutes before slicing.
Slice the steak into bite size pieces and toss with the cooled sauce. Garnish with green onions, if desired.
Notes
If making with steak tips, you can broil as above or pan sear. To do so, heat 1 tablespoon avocado oil in a hot pan over medium-high heat. Add the beef and cook until browned on all sides cooked to your liking, about 7 minutes for medium-rare (125ºF). Remove to a plate and set aside.To make this for a protein sparing modified fast, use only one tablespoon of avocado oil for greasing the pan and roasting the beef.Nutrition with 1 tablespoon oil: Calories: 418 cal, Carbs: 4g, Fiber: 1g, Fat: 18g, Protein: 55g
