Roasted & Herbed Potato Carrot Shallot Medley by Now We're Cooking!

This is my own mash-up (pardon the pun) inspired initially by a recipe from Giada De Laurentis. G's recipe involved parsnips and brussels sprouts, not my combination of potatoes or shallots. However, because I would like to stay with Max a while longer, I know better than to foist either parsnips or brussels sprouts.
