Egg Sandwiches for a Crowd

1. Preheat oven to 400 degrees with rack in center.

2. In a large bowl, whisk together eggs, cream, 3/4 teaspoon salt, and 1/4 teaspoon pepper. Stir in turkey, spinach, half the bacon pieces, and 3/4 cup cheese. Pour into a buttered 9-by-13-inch baking dish. Sprinkle with remaining half of bacon pieces and 3/4 cup cheese.

3. Bake until set, 18 minutes. Switch oven to broil and cook until browned in places, about 3 minutes more. Let cool slightly.

4. Meanwhile, stir together equal parts mustard and mayonnaise. Slice frittata into 8 rectangles. Serve between or atop slices of toast with Dijonnaise.

Cook's Notes

To toast lots of bread t one time, broil slices on a rimmed baking sheet until they're golden, about 2 minutes per side.
