1. Peel the potatoes and cut into thick rounds. Cut the tuna into pieces roughly the same size as the potatoes. Cut the peppers into strips.

2. Heat the oil in a flameproof casserole over medium heat. Add the onion, garlic, and bay leaf and cook, stirring often, for about 5 minutes, or until the onions are translucent. Stir in the potatoes. Add cold water to cover and season with salt and pepper. Bring to a boil and cook about 10 minutes, or until the potatoes are almost tender. Add the tomatoes and cook for 5 minutes.

3. Reduce the heat to medium-low. Add the tuna and cook for 5 minutes. Add the peas and pepper strips and simmer for 10 minutes. Sprinkle with parsley. Ladle into soup bowls and serve hot.
