Chop the first six ingredients, (you can hand chop, or chop them in the bowl of a food processor with the chopping blade.) Divide the vegetables in half.
Puree the garlic, lemon juice, jalapeno, vinegar, olive oil, salt, and pepper together in a blender or food processor. Add a little tomato juice if there’s not enough liquid to process.
Add 2 cups of tomato juice and half the vegetables to the blender and puree until smooth.
Tear up the bread and add it to the blender. Add remainder of tomato juice and puree until smooth. Serve soup in bowls and add remaining chopped vegetables and croutons as toppings.
