Step 1

To prep and freeze: Combine zucchini, corn, onion, garlic, chiles, chili powder, cumin, oregano, pepper and salt in a 64-ounce round, freezer-safe container. Layer the chicken on top, then the beans. Seal and freeze until ready to use, up to 3 months.

Step 2

To cook: Let the frozen soup mix stand at room temperature for 10 minutes. Invert the frozen soup mix into a multicooker (the beans should be at the bottom of the pot). Add broth and water. Lock lid in place and cook at high pressure for 30 minutes. Allow the pressure to release naturally.

Step 3

Transfer the chicken to a cutting board and shred. Return the chicken to the pot and stir in cilantro. Serve topped with additional cilantro, lime wedges, sour cream and diced avocado, if desired.
