Combine the chicken, peppers, onion, garlic, chili powder, cumin, tomatoes, beans and salt in a freezer bag and freeze flat for up to 3 months.
Thaw the bag completely in the refrigerator for 24 to 36 hours; never thaw poultry on the counter.
Empty the mixture into a 6-quart crockpot, stir in the broth, and cook covered on low for 5 to 6 hours.
Check that the largest chicken pieces reach 165°F; break one open to confirm an opaque center.
Stir in lime juice and rest uncovered 10 minutes to keep peppers and beans distinct in the broth.
