Season pork with Adobo. Place pork and pigs’ feet in large pot; cover with cold water (about 16 cups). Bring water to a boil over medium-high heat; skim off any foam that rises to the surface. Add cilantro and Sazón. Lower heat to medium-low and simmer, uncovered, 1 hour. Season chicken with Adobo. Add chicken to pot; bring water to a boil, skimming foam. Lower heat to medium-low and simmer, covered, until chicken is cooked through and pork is tender, about 30 minutes more.
Meanwhile, in a small saucepan, bring guajillo chiles and 4 cups water to a boil. Lower heat to medium-low and simmer until chiles begin to soften, about 5 minutes. Remove pot from heat and let sit until chiles are soft, about 20 minutes.
Tear chiles into pieces. Transfer chiles, chile-soaking liquid, onions, garlic and allspice to a blender; puree until smooth. Strain chile mixture through medium-mesh strainer, discard debris; set aside.
Using tongs, transfer pork and chicken to bowl; discard cilantro. When meat is cool enough to handle, shred into small pieces. Discard skin, bones and cartilage. Transfer meat back to broth; stir in hominy and guajillo sauce. Bring stew to a boil; lower heat to medium-low and simmer, uncovered, until flavors come together, 5–10 minutes more. Season with Adobo.
Serve Pozole in large, deep bowls with toppings on the side.
Leftovers? No problem! Simply spoon room-temperature soup in 1 cup measures into freezer-safe, zip-top bags. Lay the bags flat in the freezer and freeze for up to 6 months.
