2 T. olive oil

1/2 c. coconut palm sugar

  1. Place flank steak and cornstarch into a zip bag and seal. Shake the bag to evenly coat the flank steak with the cornstarch. Allow to steak rest for 10 minutes.
  2. Heat olive oil in a large skillet over medium-high heat. Cook steak until evenly browned, 2-4 minutes.

Optional: If you like a kick you can throw in a few dried hot peppers.

In the directions, you mention to add bell peppers. I don’t see those listed in the ingredients? How much bell pepper should be added?

After reading the ingredients, I cannot figure what makes the sodium content so very high. What am I missing.

I checked the website for KAME Hoisin sauce and it is not gluten free. The ingredients on the Kame website clearly say wheat flour. I am having a very hard time finding gluten free hoisin sauce, may have to make my own.

You give the nutritional information. However, what is serving size, and how many does this feed?

Thank you! I just saw it soon after I asked my question. By the WAY! This was an amazing meal. I am gluten intolerant and good chinese food is what I miss most. I made this for dinner with what meat we had on hand….Top Sirloin, added extra garlic (I LOVE GARLIC), shredded carrots and tripled the green onions (another of my favorites). IT was amazing, and tasted like what I used to eat out at a chinese place. Even my gluten eating husband loved it! WInner! This is going on the monthly menu!
