3 cloves garlic
¾ tsp. cumin
¾ tsp. oregano
¼ tsp. pepper

1 can diced green chilies (4 oz.)
10 corn tortillas
1 ½ lb (approx. 4) chicken breasts cooked and shredded
1 avocado
2 tbs. chopped fresh cilantro
Salt to taste

Saute the first six ingredients for 1 minute. Add the broth, tomatoes, and chilies. Stack the tortillas and cut into 1/8 inch strips. Add the strips to the boiling broth.
