small yellow onion, chopped
plus 2 teaspoons Dijon mustard
flat-leaf parsley, chopped
7-ounce jar roasted red peppers, cut into 1/2-inch pieces
kosher salt and pepper
white wine vinegar
extra-virgin olive oil
- Heat oven to 400° F.
- Combine the turkey, onion, bread crumbs, egg, Parmesan, 2 tablespoons of the mustard, the parsley, red peppers, 3/4 teaspoon salt, and 1/2 teaspoon pepper in a large bowl. Shape the meat into an 8-inch loaf and place in a baking dish. (See Tip, below.)
- Bake until no trace of pink remains (internal temperature should be 165° F), about 45 minutes. Transfer to a cutting board and let rest 15 minutes before slicing.
- Whisk together the remaining mustard, the vinegar, oil, 1/4 teaspoon salt, and 1/4 teaspoon pepper in a small bowl.
- Divide the greens among individual plates and drizzle the vinaigrette over the top. Serve with the sliced meat loaf.
