Melt butter in large deep skillet over medium-high
heat. Add pork;
brown on all sides, about 5 minutes total. Add
parsnips, squash,
onions, broth, and thyme; bring to boil. Reduce
heat to medium-low.
Cover and simmer until pork is just cooked through,
about 10 minutes.
Transfer pork to plate and tent with foil to keep
warm.
Continue simmering, uncovered, until vegetables
are tender and
liquid is slightly reduced, about 5 minutes longer.
Stir mustard into
sauce. Season to taste with salt and pepper. Cut
pork diagonally into
1/2-inch-thick slices and serve with sauce and
vegetables.
