Super Greens Lasagna with Smoked Sturgeon
Recipe adapted from Chef Tom Walton

INGREDIENTS
750 grams cottage cheese
1 1/2 cups finely grated parmesan cheese 
1/2 cup pesto
1/3 cup vegetable stock
salt, pepper
4 tbsp olive oil
1 leek washed well, finely sliced
3 cloves garlic, roughly chopped
1/2 bunch kale and rainbow chard
4-6 fresh or cooked lasagna sheets
10-12 oz Tsar Nicoulai Smoked Sturgeon, cubed

DIRECTIONS
1. In a large bowl, combine the cottage cheese, 1/2 the parmesan, 1/2 the pesto, vegetable stock, and a little pepper. Set aside (blend a little with an immersion blender if the cottage cheese curds are very large)
2. Place a large frying pan over medium heat and add half the oil. Add leek and garlic to the pan and sauté until softened, about 2-3 minutes. 
3. Add the kale and chard leaves, some salt, and sauté until wilted (you can cover with a little and allow to cook for 4-5 minutes. Transfer to a bowl and let cool. 
4. Preheat oven to 425F
5. Spoon 1/3 of the cottage cheese into a baking dish followed by half the greens, half the sturgeon. Sprinkle some parmesan on top, then add a layer of lasagna sheets. Repeat the layers, topping the final lasagna sheets with the remaining cottage cheese and a good sprinkle of parmesan cheese. 
6. Drizzle with remaining olive oil and bake for 30-35 minutes. 
7. Serve each piece with a some of remaining pesto spooned over.
