If you pre-bake the tomatoes with garlic and chili peppers to prepare the soup, then the soup will turn out to be unusually fragrant and spicy.
Cut the tomatoes into 2-4 parts and put in a baking sheet, drizzle with oil, season. Add finely chopped chili (without seeds), crush the garlic. Mix. Bake 15 min. at 220
Break the bread into small pieces and put in another baking sheet, salt, drizzle with oil, mix and put in the oven for 5-10 minutes.
Coarsely chop the onion. Heat a heavy bottomed pan, add a little oil, put the onion. Salt. Cook, stirring, 5 min.
Sprinkle some balsamic vinegar over the onions. Transfer the tomatoes to the onions. Add basil. Boil 5 minutes. Grind the soup with a blender (or in a food processor). Serve with crackers. Enjoy your meal!
