Step 1

Put a baking sheet in the lower third of the oven and preheat to 425 degrees F. Whisk the eggs, half-and-half, 3/4 teaspoon salt and ¼ teaspoon pepper in a large bowl and set aside.

Step 2

Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Add the spinach, artichoke hearts and 2 pinches salt. Cook, stirring, until the spinach is wilted and the skillet is dry, about 1 minute. Remove the vegetables to a plate lined with a few layers of paper towels; let cool slightly. Carefully pull up the sides of the paper towels and squeeze out most of the liquid; stir the vegetables into the egg mixture.

Step 3

Scatter the goat cheese in the bottom of the pie crust. Pour in the egg mixture, then arrange the tomatoes cut-side up in the eggs. Season with pepper. Carefully place the quiche on the hot baking sheet and bake until set, about 30 minutes.

Step 4

Meanwhile, whisk the vinegar and mustard in a medium bowl; whisk in the remaining 1 tablespoon olive oil until smooth. When the quiche is almost done, add the salad mix to the bowl and toss with the vinaigrette. Season with salt and pepper.

Step 5

Cut the quiche into wedges and serve with the salad.
