  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.

wish you had diabetic croclk pot recipes


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?


Where is the best place to find al he Asian condiments


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


What can I use in place of tamari if I can’t find?


do you cut the flank steak up or do you put it in the crock pot hole .


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?
