Here’s a great way to use up any leftover vegetables sitting in your refrigerator. If you don’t have the vegetables used here, feel free to substitute any sturdy veggie you have on hand, such as carrots, fennel, parsnips, and eggplant.

Roasting deepens and intensifies the inherent sweetness of vegetables; so don’t be surprised if this becomes a new family favorite!

Tip: This recipe calls for Herbs de Provence, but Italian seasoning can be used instead. This will alter the flavor profile a bit, but the result will still be delicious.
