Add the celery, yellow peppers, red peppers, and jalapenos, and saute an additional 5 minutes. Add the garlic and saute an additional 2 minutes. When the black-eyed peas are tender, add the sauteed vegetable mixture, chopped parsley, salt, pepper, and cayenne pepper, and stir well to combine. Cover and set aside for 5-10 minutes to allow the flavors to blend. Taste and adjust seasonings, if needed.
Place garnishes in separate small bowls.
Garnish individual servings with choice of sliced green onions, diced tomatoes, shredded cheese, and a few dashes of hot pepper sauce, as desired.
