Fry the ginger in a wider saucepan over medium heat, add cauliflower florets and stir-fry for 1 minute. Deglaze with the broth, mix in the chilli and cook gently for about 3 minutes with the lid closed.
Add the diced paprika and spring onions and simmer for about 5 minutes. The cauliflower shouldn`t get too soft.
Mix the cornstarch with a little water and bind the sauce in the pot with it. Season to taste with salt, pepper and sugar.
