Brown the sausage in a large saucepan over medium heat. Add the onions, salt, cayenne, garlic cloves, thyme, bay leaves, and parsley. Cook, stirring, until the onions are wilted, about 5 minutes. Add the stock, peas, and garlic. Bring the mixture to a gentle boil, then reduce the heat to medium-low and simmer, uncovered, until the peas are tender, about 1 1/2 hours.
Remove the bay leaves and serve warm.
