Skin and chop tomatoes. Cut bread without crust into pieces.
Heat the oil in a saucepan, sauté the finely chopped garlic, add the bread and let the oil soak up. Add the tomatoes and let simmer for a few minutes. Add the stock and basil (do not chop!), Season with salt and pepper. Simmer for about 30 minutes, stirring occasionally, cover again.
When the soup is ready, remove the basil and serve hot.
