Cut the tortillas into 1” squares, using a pizza cutter or knife.
2 large flour tortillas
Carefully add the tortillas to the soup. Gently press them down but do not stir vigorously as they will tear.
Bring the mixture to a boil again, then reduce heat, and allow to simmer for 15 minutes.
Remove from the heat, gently stir in the milk, and allow cool for 10-15 minutes before serving.
1 cup milk
Notes
Place leftovers in an airtight container and store them in the fridge for up to 5 days. Or you may store it in the freezer for up to 2 months (freezer bags work well for this).
