Prepare the crust. Using a food processor, finely grind oyster crackers. To the cracker crumbs add the melted butter and 1/2 cup grated cheddar cheese. Mix these ingredients together until smooth. Press mixture into the bottom and up the sides of a pie plate. Store in the refrigerator until ready to use.
Preheat oven to 350°F.
Cook the bacon in a skillet over medium heat, cook until almost crispy, set aside. Pour off all but 1 tbsp fat. Add onions and saute for 3 minutes or until onions are lightly browned. Add kale and saute for 2 minutes or until fully wilted. Remove from the heat.
In a large bowl, beat eggs with cream until uniform, and season with salt, pepper and nutmeg. Add the bacon, onion and kale mixture and stir until combined. Stir in 1 cup grated cheddar cheddar.
Pour mixture into prepared pie shell and spread into an even layer. Use a fork to lightly stir, making sure that liquid is well distributed.
Bake for 30-35 minutes or until filling is set. Let stand 10 min to firm up before serving. Enjoy!
