Your dish sounds nice but to add more sauce and herbs you could do this: bake a bit extra in the oven and before serving, Mash some of the veggies in a large saucepan. add some water so they don't stick while cooking over a lo/med heat. Then add some butter and fresh herbs along with any extra salt and pepper. Now would be a good time to put in the balsamic vinegar. Serve over the roasted veggies as your sauce. Also, there is a item at most health food stores called Brags Liquid Aminos- it is a fermented product and very good for you and works VERY nice with veggies and sauces.
