Heat oil in a large stockpot over medium-high heat. Add boar and brown evenly. Drain off any fat or liquid rendered during browning. Add 1 1/2 quarts chicken broth and any additional broth or water to cover meat and bring to a boil. Reduce heat and simmer, covered, for 2 hours or until meat is tender and breaks apart, but doesn’t fall apart with moderate finger pressure. Drain liquid from stockpot. Add remaining 2 cups of chicken stock and all other ingredients except cilantro. Simmer until peppers are tender. Stir in cilantro and season with salt and pepper to taste.
