Heat oven to 325˚F.
Heat a large, high-sided skillet or Dutch oven over medium to medium-high heat with EVOO, a couple of turns of the pan. Add the sausage, crumble and brown 3-4 minutes then add peppers, onions and garlic, and season with salt and pepper. Cook 5 minutes more so the vegetables start to soften.
Add tomatoes, stock and bay leaf, stir and bring up to a boil. Add shrimp and cover with a tight-fitting lid. Cook 5 minutes, uncover and stir in basil and parsley. Turn off heat.
Crisp bread in the hot oven. Serve stoup in shallow bowls with crusty bread alongside for mopping.
