Preheat your oven to 400°F and toss the chopped kale with one teaspoon of olive oil and a pinch of salt on a baking sheet.
Roast the kale for 8-10 minutes until the edges are crispy and slightly darkened.
In a small bowl, whisk together the pumpkin puree and Greek yogurt with a pinch of cinnamon and salt, then warm gently in a small saucepan over low heat.
Heat a cast-iron skillet over medium-high heat with the remaining teaspoon of olive oil.
Season the venison loin with salt and pepper, then sear for 3-4 minutes per side for medium-rare; let the meat rest for 5 minutes before slicing.
While the meat rests, soft-boil or poach the egg until the white is set but the yolk remains runny.
In a small pan, simmer the blueberries with a splash of water or balsamic vinegar until they burst and form a light glaze.
To plate, spread the pumpkin-yogurt mixture on the base, top with sliced venison and the jammy egg, and serve alongside the roasted kale, sauerkraut, and berry reduction.
