This delicious side dish can also be served as an appetizer by spooning portions atop thin, small slices of fresh, rustic bread.
1 medium onion, finely chopped 1/2 cup crumbled feta cheese 1/2 cup grated Edam cheese 1/4 cup crumbled blue cheese 2 tablespoons chopped fresh dill 1/4 teaspoon ground nutmeg 2 tablespoons fresh bread crumbs 1 egg yolk 3 tablespoons olive oil 2 (10-ounce) packages ready-to-use fresh baby spinach 2 tablespoons grated Parmesan cheese
Preheat oven to 350*C (175*C). Lightly butter a 12-inch oval gratin pan or an 11 x 7-inch baking dish.
Mix onion, feta cheese, Edam cheese, blue cheese, dill, nutmeg, bread crumbs, egg yolk and nutmeg in a small bowl. Set aside.
In a large pot or Dutch oven, heat olive oil over medium-high heat. Add spinach and saute until wilted and juices evaporate, about 3 minutes. Transfer to strainer; drain well. Shake strainer up and down to remove as much liquid as possible.
Arrange spinach in prepared baking dish. It will make a thin layer. Top with onion mixture. Sprinkle with Parmesan. Bake until heated through, about 20 minutes.
Heat broiler. Broil spinach, about 6 inches from broiler element, until cheese is golden brown on top, watching closely to prevent burning, about 2 minutes.
Serve warm or hot..
