Greens and Onion “Souffle”

Preheat oven to 350 degrees. Lightly spray a 9- by 13-inch baking dish with nonstick cooking spray.

Cut the onion in half and then slice thinly into half-moons. Heat the olive oil in a large skillet over medium heat. Add the onion and cook for 6 minutes, or until soft.

Add the greens and toss with tongs until wilted, about 3 minutes. You may need to cook the greens in batches.

Transfer to a large mixing bowl. Stir the ricotta, goat cheese, eggs, flour, salt, black pepper, and cayenne pepper into the greens. Pour into the prepared dish.

Bake for 45 minutes, or until set and puffed.
