How to Store Your Mongolian Beef Freezer Meal:

  1. Combine the ingredients for the sauce and put it in a Ziploc bag, quart size.
  2. Add the cornstarch-coated raw steak pieces to a separate freezer bag, gallon size.
  3. Remove excess air from bags, seal, and freeze.

Oh, don’t forget to label the bags and keep them together so you know what they are. You can then thaw it all later and cook it in your slow cooker! So easy.
