Boil the chicken Breast till it's done.

shred the chicken

Fry the toritallas a bit, make sure they are still soft.

in the same frying pan, heat up the tomato sauce with 1/4 of the onion in there.

Continue frying the tortillas in the frying pan with tomato sauce.

they still have to be soft, so once they are smothered in tomato sauce fill the tortilla up with chicken and roll it up

I like to add white cheese and some salad on top.

They should be all done. I like yi serve with rice. Enjoy!
