Mix all ingredients (except tortillas, cheese, avocados
, and cilantro) together in a large, heavy saucepan
. Bring to a boil over medium-high heat, stirring frequently. Reduce heat to medium-low, cover and simmer
for 30 to 45 minutes, stirring occasionally. Shred
the pork, using 2 forks, or mashing with a potato
masher. Put shredded pork back into sauce and mix ingredients. Cover up and cook on low for another 10 to 15 minutes.
In a large skillet over medium heat, cook a tortilla about 2 minutes on each side. Spoon some pork onto the tortilla and top with 4 to 5 avocado pieces and cilantro
. Heat up another tortilla until toasted and add cheese. Cook until cheese
is melted. Place the second tortilla cheese side down on top of the pork and avocado. Cut into 4 slices and repeat process. Garnish
with cilantro and serve.
