Cut the bread into small pieces, like regular stuffing.
Combine rosemary, thyme, sage, parsley, and salt in a separate container. Chop all vegetables.
Warm a small saucepan and sauté the onion, celery, and carrots over medium heat with 1/4 cup broth (Add the broth it little by little so the vegetables don't stick you may not need it all). Add these veggies to the bread. Add the herbs to the bread as well.
Drizzle the vegetable stock over the bread and veggie mixture.
