Prepare and cut the cabbage, onion, carrot, bell pepper, and celery into bite-sized pieces.
Add olive oil to a pot and sauté the onion, carrot, and celery first.
Add the remaining vegetables and continue to stir-fry, then pour in water.
Add the canned tomatoes and seasonings (salt, pepper, cayenne pepper, bay leaf, etc.), then let it boil.
Once it starts boiling, cook over medium heat for 20–30 minutes until the vegetables are cooked through.
Taste and adjust the seasoning if needed, then serve in bowls.
