Combine the shallows, stock, cumin, paprika, and pork in a small saucepan. Bring to a simmer then reduce heat to low. Cover and simmer 30 minutes.
Remove the pork from the pan and set aside. Increase the heat to medium and cook for 8 minutes or until liquid is reduced to 3 tablespoons.
Shred the pork using 2 forks then return the pork to the pan with the simmering liquid. Add in the beans and garlic cloves and mix to combine.
Meanwhile, combine the cabbage, cilantro, 1 tablespoon lime, oil, garlic, and pepper. Toss to combine.
In a small bowl combine cumin, salt, yogurt, avocado, and remaining lime juice. Mash until desired consistency is reached.
To assemble divide the pork and bean mixture into the tortillas then top with a heaping tablespoon of slaw and a few teaspoons of avocado sauce. Serve.
