In a large pot, heat the olive oil over medium heat. Add the chopped onion and minced garlic. Sauté until the onion becomes translucent, about 5 minutes.
Add the chicken thighs to the pot and brown them on both sides for about 5-7 minutes.
Pour in the chicken broth and bring to a gentle boil. Reduce the heat, cover, and simmer for about 30 minutes, or until the chicken is cooked through and tender.
While the chicken is cooking, prepare the verde sauce. In a blender, combine the tomatillos, cilantro, jalapeños, ground cumin, and salt. Blend until smooth.
Once the chicken is cooked, remove it from the pot and shred it using two forks. Return the shredded chicken to the pot.
Stir in the hominy and the verde sauce. Simmer for another 15 minutes to heat through and meld the flavors. Adjust salt and pepper to taste.
Serve the pozole hot, garnished with lime wedges, sliced radishes, and diced avocado. Add tortilla chips for crunch.
