Preheat oven to 350.
Combine all ingredients except the enchilada sauce and olive oil until well mixed.
Form meatballs into desired size (I got about 17 meatballs in my batch).
Heat oil in oven proof skillet over medium heat. Working in batches, place 6-10 meatballs, depending on the size of your skillet, and brown on each side (3-5 minutes per side) over medium heat. Set meatballs aside, and continue searing the rest of your meatballs. Do not crowd your pan, otherwise the meatballs will steam and not get the caramelized edge you want.
Once all the meatballs are browned, pour sauce into the pan, scraping up any brown bits. Bring to a boil over medium, and remove from the heat.
Place meatballs back in the sauce, and bake for 20 minutes or until meatballs reach an internal temperature of 165.
Serve with cojita, lime wedges, cilantro, scallions, serano peppers, pickled onions, tortilla chips, etc!
