Slice and dice veggies. Larger pieces for soft veggies (like squash and zucchini), smaller pieces for dense veggies (like sweet potatoes). Toss with fresh herbs, olive oil, parmesan cheese, and seasonings. Spread in a single layer on baking sheets. Roast for 30 - 40 minutes until tender and edges just begin to brown.
For the soup...
When the veggies are tender, remove from the oven, discard large herb stems then transfer into your favorite soup pot.
Add diced tomatoes (preferably no-salt added) and broth, bring to a gentle simmer. Season to taste with dried herbs. Serve with a sprinkle of parmesan cheese.
