Place the chicken thighs in a large pot, then add the chopped onion and minced garlic.
Pour in the chicken broth and apple cider vinegar.
Sprinkle in the chili powder, cumin, oregano, smoked paprika, sea salt, black pepper, cinnamon, and bay leaves. Stir everything together and bring to a vigorous boil over medium-high heat.
Once boiling, lower the heat to a gentle simmer, cover the pot, and cook for about 45 minutes, or until the chicken is tender and easily shreds apart.
Carefully remove the chicken from the pot and shred it using two forks. Return the shredded chicken to the pot, stirring it back into the flavorful broth. Let it simmer for an additional 10 minutes.
While the chicken is simmering, heat a skillet over medium heat and toast each corn tortilla for approximately 30 seconds on each side until warm and flexible.
Take a generous scoop of the chicken mixture and place it on each tortilla. Garnish with fresh cilantro and diced onion.
Serve the tacos alongside lime wedges and sliced radishes for a refreshing crunch. Enjoy!
