It’s a French classic “Soup au Pistou” for which you gently cook very fresh summer vegetables in either water or stock, and stir in a paste (“pistou”) of basil, garlic, and tomatoes. This soup is similar to a light Italian minestrone, but without the white beans, and with a pistou “pesto” for flavor. It’s simple, light, healthy, and delicious. Clean eats that taste amazing! Dad makes the soup several times each summer, especially when the garden is producing a lot of summer squash and tomatoes. It’s a great way to use up garden produce. Using gluten-free stock or bouillon makes this a gluten-free soup.
