Heat pan to medium-high heat. Add 4 tablespoons of butter and halved mushrooms. Cook for 5 minutes. Add salt and cook for 1 more minute. Add garlic and cook for 1 more minute. Add soy sauce and deglaze the pan. Turn off heat and remove from pan.
In the same pan as the mushrooms were cooked, add olive oil and 2 tablespoons of butter. Add in frozen cauliflower gnocchi. Cook on medium heat for 5 mins, don’t touch them. Gently flip and cook for another 5 mins. You want them to develop a nice crust on both sides. Season with salt. Remove gnocchi to a plate.
Add 2 tablespoon butter, half and half, Parmesan cheese, ½ teaspoon sea salt, and cooked mushrooms back in the pan. Scrape all the bits that were stuck in the pan, that’s flavor. Let the sauce reduce for a minute and add the gnocchi back in and cook for one more minute.
Add the rest of the Parmesan and chives. Serve hot.
