Mustard-Roasted Potatoes

**Thanks to Kira J. for these next 6 recipes! They look delicious!

2 1/2 pounds small red potatoes

2 yellow onions

3 tablespoons good olive oil

2 tablespoons whole-grain mustard

kosher salt

1 teaspoon freshly ground black pepper

1/4 cup chopped fresh flat-leaf parsley

Preheat the oven to 425.

Cut the potatoes in halves or quarters, depending on their size, and place them on a sheet pan.  Remove the ends of the ions, peel them, and cut them in half.  Slice them crosswise in 1/4 inch-thick slices to make half-rounds.  Toss the onions and potatoes together on the sheet pan.  Add the olive oil, mustard, 2 teaspoons salt, and the pepper and toss them together.  Bake for 50 minutes to 1 hour, until the potatoes are lightly browned on the outside and tender on the inside. Toss the potatoes from time to time with a metal spatula so they brown evenly.  

Serve hot sprinkled with the chopped parsley and a little extra salt.
