Recipe Tips

If desired you can replace the mushrooms with a different protein, meat, or tofu.

You could also just add some shredded chicken or tofu to the recipe as you are assembling it.

I recommend warming the tortillas in the skillet using butter instead of oil because the butter makes them so crispy and extra delicious.
