This is another one by Kate (age 10). She adores mushrooms and seasoned this one herself. She also loves the sound of 'tarragon' so into the soup it went. It warmed my heart; I knew it was an excellent choice. It turned out delicious!
She thickened the soup using a can of white beans blended with 3 c. vegetable stock. She grilled the mushrooms with onions and garlic, mixed the two, simmered it for a few minutes, and lunch was ready in less than 15 minutes.
