Boil the tomatoes, chili pepper, garlic, and onion.

Once cooked, transfer to a blender and blend until smooth.

Strain the blended mixture and fry it in a pot until it comes to a boil, about 3 minutes.

Meanwhile, cut the tortillas into thin strips and fry them until crispy.

After 3 minutes, add water and salt to taste to the pot.

To serve, top with cheese and avocado.
