In a large pot, heat a splash of olive oil over medium heat. Add the sliced yak sausages and cook until browned.

Add the chopped onion and minced garlic to the pot and sauté until translucent.

Add the diced potatoes and chicken broth. Bring to a boil, then reduce heat and simmer until potatoes are tender.

Add the torn kale and continue to simmer until the kale is wilted and tender.

Stir in the cream and season with salt and pepper. Heat through.

Serve hot, garnished with a sprinkle of Parmesan cheese if desired.
