Set a 6-quart Instant Pot to sauté. When hot, add the olive oil and heat.
Add the onion, celery, carrot, and cabbage. Sauté, stirring occasionally, until the onions start getting soft.
Add the sliced sausage and garlic. Sauté for 1-2 minutes.
Add the chicken stock, black-eyed peas, diced tomatoes, kale, parsley, hot sauce, bay leaf, red wine vinegar and cumin.
Press “cancel” to turn off the sauté function. Press “manual” and use the “+” and “_” buttons to set the Instant Pot to cook for 5 minutes. Set the valve to seal.
When the instant pot beeps and the “L000” screen comes up, do a quick release by carefully turning the valve to let the steam out.
Remove the bay leaf and add salt and pepper to taste, optional.
Serve warm and sprinkle on optional chopped parsley.
