Flour tortillas on the bottom of a slow cooker.

Spray your slow cooker with nonstick cooking spray and line the bottom with flour tortillas. You can use corn tortillas instead of flour tortillas if you’d prefer or if you need to keep it gluten-free.

The flour tortillas tend to soak up a little more moisture from the meat mixture, so you can use corn tortillas as another option, if you’d like to.
