Gratin Italian sausage and kale

I love teasing people about kale. It's the new kid on the block and folks are still discovering it and getting that shiny new convert look when you tell them it's survival food (ie. people eat it when there's nothing left to eat). The truth is that 1) I like kale just fine and 2) it is not new food. It's been around for a long, long time because it's so hardy and reliable. Cook it right, and it's a sweet treat. But it does have a very strong flavor and not everyone is a fan, so if you want to serve kale to a finnicky table, match it with equally strong flavors. This dish is a cheesy saucy gooey warming dish with a lovely crunchy topping.

Some olive oil

1 lb fresh mild or hot Italian sausage, casings removed and crumbled

⅓ cup dry white wine

2 bunches (about 1 pound) kale, stemmed and torn into large pieces

½ cup (4oz/114gr) + 3 Tbsps (1.5oz/42gr) butter, melted

⅓ cup flour

2 cups milk

8oz fresh goat cheese or feta

3oz freshly grated Parmigiano-Reggiano

1 cup fresh bread crumbs

1 Tbsp minced fresh herbs (such as a combination of parsley, oregano and basil)

1. Heat the oven to 350°F degrees.
2. In a large stainless steel sauté pan, heat the oil and cook the sausage, breaking it up. Cook until browned (usually when the moisture has evaporated). Remove any excess fat.
3. Add the wine scraping up the fond. Continue to cook until the wine reduces and is mostly evaporated, 1 to 2 minutes. 
4. Decrease the heat and stir in the kale, one handful at a time. Mix in the kale and cook until it begins to wilt and turn a bright green. Don't worry about overcooking the kale; it is impossible, unless you burn it! Remove from heat and set the pan aside.
5. Meanwhile, dump the bread crumbs in a medium sized bowl.
6. Melt all the butter in a saucepan. When melted, put 3 Tbsps of it into the breadcrumb bowl.
7. Into the remaining butter, whisk in the flour; continue wisking until starting to brown. Add the milk, whisking constantly, until it thickens into a sauce.
8. Add the crumbled goat cheese to the roux and continue to whisk until the cheese is melted and the sauce is smooth.
9. Pour the sauce into the sausage and kale and let sit 5 minutes to allow any more fond to lift. Stir vigorously with a wooden spoon to scrape up the fond and mix the sauce evenly in the sausage and kale.
10. Spoon the mixture into a shallow, 2 quart gratin dish.
11. To the breadcrumb and butter, add parmesan and minced fresh herbs. Mix thoroughly, then evenly distribute over the kale and sausage to form the topping.
12. Bake the gratin until the topping is golden-brown and the filling is bubbly, about 30 minutes (briefly broil at this point if not browned enough).
13. Cool slightly before serving with crusty bread if eating as a main dish.
