Combine the tomatoes, beans, cucumber, scallion, oregano and basil in a small bowl, with salt and pepper to taste. Mix well and set aside for one hour. For the rouille, in the bowl of the food processor, combine the garlic, red pepper, egg yolk, lemon juice, and paprika. Pulse until smooth, then slowly drizzle in the oil and process until the mixture thickens. Season with salt. For the bread, brush both sides with a little olive oil and broil or grill both sides till golden brown. Cut the garlic in half and rub on one side of each slice. Top the grilled bread with the bean and herb mixture, and a dollop of the rouille. Top with sea salt, drizzle with good olive oil.
