Cover the chicken with water, add onion, celery and leaves, pinch of salt, peppercorns if desired, and a pat of butter (don't ask me why, my mom always did). Stew chicken until done.
Allow to cool and remove skin. Shred chicken.
Add chicken and stock to large pot. Add salsa and seasoning.
Add thawed vegetables. I usually use corn, green beans, and peas that I've frozen from the farmer's market, but you can use supermarket frozen or even canned vegetables. Use any combination of veggies you like. It's adaptable!
Add shredded cabbage and simmer soup for at least 30 min. Taste and add Cholula or other hot sauce as desired.
If I'm not dieting, it's good with tortilla strips on top. I also stir in some fresh cilantro before serving.
