It’s actually very simple

• Fry onion on oil
• Add 1kg of any mushrooms (in my case it was oyster mushrooms + champignons, roughly 1:1 )
• Fry a bit until mushrooms reduce their volume
• Add 3 tbsp of ground paprika, a bit of ground cumin, salt and black pepper
• Cover the pot and cook for 10 min
• Add mixture of 200 ml almond milk + 200 ml soy cream + 2 tbsp of flour
• Cook uncovered for another 10 min
• Done. The dumplings are just a mixture of 350g of flour and 300 ml of water (and salt)

And it was absolutely delicious :) I was actually surprised how good it turned out

EDIT: Original recipe in Slovak if it helps. I did some changes though (f.e. replaced butter with oil or used regular flour for dumplings)
