Cover shredded chicken with chicken stock. Add a small pinch of salt and pepper. Slowly heat to a simmer and cover. Do not boil. Simmer for 2-3 minutes, or until chicken is thoroughly heated.

Whisk together avocado, shallot, and half of the lemon juice in a small mixing bowl. Season lightly with salt and black pepper.

Drain chicken and reserve stock. Cover with remaining lemon juice.

Spread a thin layer of the avocado puree on each tortilla to hold the filling in place.

Garnish each taco with lemon zest, shredded cheese, and parsley.
