When I was training to be a chef we used to make minestrone. The golden rule, the head chef told me, was there should be so much veg that, once cooked, the wooden spoon should stand up in the centre of the pot. With that in mind, try this summer vegetable soup packed with lots of veg plus flavours such as ginger, lemongrass and oregano. You can add a little dried spaghetti or rice to make another variation, if you want.
