Roast carrots and mushrooms: Preheat oven to 425F. In a large bowl combine olive oil, balsamic, thyme leaves, salt, paprika and pepper. Add carrots and mushrooms and toss/rub to coat with seasoning. Arrange the vegetables in a single layer on one or two large baking sheets, and roast for about 20 minutes or until vegetables are browned in spots and carrots are easily pierced with the tines of a fork. (If using larger carrots they’ll take longer to cook. To shorten cooking time, cut each half lengthwise again to make them thinner.)
Cook lentils: While vegetables are roasting, add lentils to a small saucepan along with kosher salt, crushed garlic clove, bay leaf, and stock or water to cover the lentils by one inch. Bring to a boil over high heat, reduce to a bare simmer and cover partially with a lid. Simmer lentils just until tender but still toothsome, about 20 minutes. Drain lentils, discarding garlic clove and bay leaf. Toss lentils with sherry vinegar and olive oil, and season to taste with salt and freshly ground pepper.
Make parsnip puree: While lentils are cooking add parsnips, garlic and milk to a medium saucepan and bring to a boil. Reduce heat to simmer, cover with a lid, and cook until parsnips are tender, about 10 minutes. Using a slotted spoon, transfer parsnips and garlic to blender. Add about two thirds of the cooking liquid and ¼ teaspoon salt. Blend until smooth, adding more cooking liquid as necessary to achieve desired consistency. Add 1 tablespoon olive oil or butter and more salt to taste if desired, and puree just until silky and glossy. Don’t over-process the parsnips or you may end up with wallpaper paste.
Serve: Divide parsnip puree, lentils and roasted vegetables into four servings and distribute evenly among plates. Dollop with carrot top pesto, and garnish with minced chives, carrot fronds or parsley if desired.
Notes
If you don't have good aged balsamic vinegar, simmer regular balsamic in a saucepan until it reduces to a thick syrup. It will store at room temperature indefinitely and has many uses, so if you're going to do this I suggest cooking down at least a half-cup of vinegar at a time. That way you'll have some on hand for next time!
