In a 5-qt stockpot, combine water with the lemon pepper, 1 tsp ground cumin, and olive oil.
Bring to a boil.
Add the chicken breast halves and return to a low boil, then reduce the heat to low and simmer 20-30 minutes or until the chicken is fork tender and the juices are clear.
Remove the chicken from the broth and cut into bite-size pieces, then return it to the broth.
Add the garlic, onion, corn, green chiles, 1 tsp ground cumin, lime juice, and Great Northern beans to the broth.
Bring to a boil.
Simmer until thoroughly heated, about 45 minutes.
To serve, ladle into soup bowls and sprinkle cheese on top.
Refrigerate any leftovers; this chili is usually even better heated up the next day.
