Swiss Chard, Ham and Cheddar Quiche

My wife was in charge of dinner tonight and with meals like this, I may have to let her cook more often!  She used around half of the Swiss chard along with onion and ham in a fantastic quiche recipe she found on a website called Real Simple.  The ham was an addition, but otherwise she followed the recipe as written.

Share contents used:
Half of the Swiss chard
All the remaining romaine (in a side salad)

Ingredients
1 tablespoons olive oil
1 bunch Swiss chard, stems removed, chopped
1 onion, chopped

1/2 cup diced cooked ham
3 large eggs
3/4 cup half-and-half
kosher salt and black pepper
2 ounces cheddar, grated (1⁄2 cup)
1 prebaked 9-inch piecrust

Preparation
Heat oven to 350° F. Heat 1 tablespoon of the oil in a large skillet over medium-high heat. Add the chard and onion and cook until tender, 3 to 4 minutes. In a medium bowl, beat the eggs with the half-and-half; season with 1 teaspoon salt and ¼ teaspoon pepper. Add the cheddar and chard mixture and mix to combine. Pour into the prebaked 9-inch piecrust and bake until set, 40 to 45 minutes.
