In a large pot, over medium heat, render the sausage for 5 minutes. Stir in the onions, salt, cayenne, garlic, bay leaves, thyme and parsley. Saute for 5 minutes, or until the onions are wilted. Stir in the chicken stock, peas and garlic. Bring the liquid up to a simmer and cook for 1 1/2 hours, or until the peas are tender. Spoon the peas and sausage in the center of a shallow bowl. Garnish with green onions. Serve with cornbread muffins.
