In a 1 gallon stock pot, heat the olive oil. When the oil is hot, render the Tasso for 2 or 3 minutes.
Add the onions, celery, carrots and continue sauteing for 2 minutes.
Stir in the garlic, bay leaves and ham hocks. Season with sugar, salt, black pepper, fresh thyme and red pepper. Add the black-eyed peas and chicken stock. Bring the liquid up to a boil, cover and reduce to a simmer. Simmer the peas for about 45 minutes to 1 hour, or until the peas are tender.
Remove the ham hocks from the pot and remove the meat. Add the meat back to the peas and adjust the seasoning as necessary.
