In a large pot or dutch oven, add chicken thighs, tomatillos, onion, jalapeños, chicken broth, oregano and sea salt. Place over high heat and bring to a boil. Reduce heat to simmer and cover partially. Cook for 40 minutes, until chicken is fall-apart tender. Transfer chicken to cutting board and shred with a fork. Set aside. Using a large slotted spoon, place the cooked tomatillos, onions and jalapenos in a large blender. Add a large handful of fresh cilantro, a cup or so of the cooking liquid and puree until completely smooth. Add the shredded chicken, pureed veggies and hominy into the large pot. Stir and cook over medium-high heat for 15 minutes uncovered. Taste and season with salt as necessary. Serve with fresh lime juice, radishes, jalapenos, cilantro and oregano.
