Pistou soup is a hearty and comforting dish from Nice, similar to the Italian minestrone soup. It is made with a variety of vegetables such as tomatoes, zucchini, carrots, and beans, cooked in a flavorful broth. The soup is finished with a dollop of pistou, a traditional Provençal sauce made with basil, garlic, olive oil, and Parmesan cheese. Pistou soup is a delicious and nutritious option for a satisfying meal.
