Calling all veggie lovers -- this stew is for you! Packed with a huge variety of veggies makes this a vegetarian dream. The addition of sourdough bread adds some extra heft to take this from soup to stew.
And, YES, you can absolutely make this in your Instant Pot.
You'll still want to blanch and drain your greens separately, and then sauté the carrots and leeks in your Instant Pot insert. Be sure to keep the sauté setting on LOW because I find it cooks much faster than on the stove.
You'll also want to have your tomatoes already crushed and waiting in a bowl, so you can add them as soon as the carrots and leeks are softened. Then add the rest of the ingredients, and Pressure Cook on the "Soup" Setting.
