Cook the chicken breast in a pot with the cilantro, garlic clove, and 1/4 onion.

Once the chicken is cooked, wash and dice the vegetables: carrot, zucchini, and chayote. Add them to the pot and cook for 10 to 15 minutes.

Remove the chicken breast and add the fideo noodles. Cook for up to 10 minutes, then turn off the heat.

Serve the noodle soup with the vegetables.
