I love this soup! It's a quick and easy vegetarian option that tastes great and is hardy. It is very easy to alter based on the ingredients on hand. I actually omit the rosemary and use frozen basil from my summer garden. I also omit the red vinegar. I use fresh vegetables from my garden in the summer and early fall, but in the winter or when I am in a pinch for time I use a frozen mediterranean mix of veggies that has zucchini, summer squash, grean beans, carrots, peppers, and onion. I have also used canned diced tomatoes when fresh are not as available.
