Salmon and Swiss Chard Quiche

Step 1
Preheat the oven to 350 degrees F (175 degrees C). Coat a 9-inch pie plate with nonstick cooking spray.

Step 2
Heat oil in a large skillet over medium heat. Add Swiss chard, mushrooms, and onion. Cook, stirring occasionally, until tender and most of the liquid has evaporated, about 10 minutes.

Step 3
Spread chard mixture on bottom of prepared pie plate. Break salmon into pieces and arrange evenly over chard. Whisk together eggs, milk, salt, nutmeg, and pepper in a bowl. Pour over salmon.

Step 4
Bake until a knife inserted in center comes out clean, 28 to 30 minutes. Cool about 10 minutes before cutting into wedges. Top with chives (if using).
