Cut the tortillas into small triangles (like chips)
Chop or shred the queso fresco into small pieces
Fry your eggs, or scramble them with a Tbsp of water per egg
Heat a skillet, and then add a ½” of oil
Add the tortilla triangles to the skillet to fry them, turning frequently, until crisp. Add more oil if needed. You may need to do this in batches.
While the tortillas are frying, fry the eggs in another skillet to a soft texture and then set aside.
When the tortillas are all done, add them all back to the skillet and add the eggs over the top.
Sprinkle with salt to taste, then add a generous amount of salsa and the cheese, stir through and give the cheese a little time to melt.
Top with sour cream and the chopped onion.
