Vidalia Onion, Kale, And Swiss Tart - cooking recipe

Ingredients

3 cups vidalia onions, sliced as thinly as possible
1/4 cup unsalted butter
1 cup kale, chopped
1 cup heavy cream
sea salt
grated nutmeg
2 eggs
1 cup grated swiss cheese
pie crust

Preparation

Roll out crust, fit into glass or ceramic quiche or pie pan. Leave enough \"overhang\" to crimp attractively. Place in fridge to chill.
Melt butter in heavy skillet, add onions, and cook until nicely browned and very soft, almost caramelized. Add kale and cook until just wilted. Add salt and nutmeg to taste.
Cool slightly. Add cream and eggs, mix well. Put cheese in bottom of crust, pour onion mixture over, and bake at 400 until puffed and golden.
Delicious served warm or cold!
