Saute some garlic and shallots in olive oil. Once its fragrant add mushrooms and cauliflower. I had a little sweet potato, which I added but its purely optional. Once they start to soften sprinkle paprika and little salt. Two tablespoons of dark soy sauce. Cook on a low heat and preferably use a silicone spatula. This will help in scrapping the pan to also mix everything well.
It may take upto 20 mins on low heat to get cooked.
Enjoy the simple Umami taste of soy sauce.
