Brown turkey in 1 tablespoon oil in 1-inch crumbles until the thickest pieces reach 165°F; transfer to a clean bowl.
Add remaining oil, onion, carrots and celery and cook 7 to 9 minutes until softened.
Add garlic, tomato paste, paprika, oregano, thyme, salt, pepper and optional red pepper and stir 1 minute.
Add broth and crushed tomatoes, scrape the pot bottom, bring to a boil and reduce to a steady simmer.
Add half the cabbage and simmer uncovered 12 minutes until tender.
Return turkey with beans and remaining cabbage and simmer gently 8 to 12 minutes until final ribbons are tender but distinct.
Remove from heat, stir in vinegar and parsley, rest 10 minutes and adjust seasoning.
