Both were, once again, delicious.
The gratin was a very basic dish. Other than needing to be able to put it in the oven an hour before eating, there isn't much to do.
First, make a basic white sauce.
Melt a tablespoon of butter in a medium pan over medium heat. Add a tablespoon of flour and stir together. Add a cup of milk and stir and simmer until it thickens up a bit. To this, add a small handful of parmesan cheese and season with salt and pepper.
Combine the cup of cooked white sauce with a cup of cooked greens. Spread it into a small buttered baking dish, and bake for about an hour at 350.
It came out creamy and sweet and delicious! It was a great side for chicken breasts.
