1. Preheat the oven to 350°F Put the bread on a baking tray and bake for 10 minutes until crisp. Set aside. 2. Cut the tough cores from the top of the tomatoes. Slice the tomatoes thinly. Put in a bowl with the chives. Whisk together the mustard, vinegar and olive oil. Season to taste and pour over the tomatoes. Mix and set aside. 3. Preheat the broiler to medium-high. Beat the goat cheese with the marjoram and garlic. Add a little black pepper and spread onto the croutons. Return to their baking tray and drizzle with a little more olive oil before setting under the broiler. As soon as they are hot - about 2 minutes - remove. 4. Distribute the tomato salad between 6 plates. Add the goat's cheese croutons and serve.
