Sweat finely chopped onions in a little oil, then add the sliced carrots and finely chopped garlic and cook for about 5 minutes over medium heat. Add the peppers cut into strips and cook for another 5 minutes. In the end, peppers and carrots should be soft with a slight bite.
Deglaze the vegetables with soy sauce.
Add coconut milk and spices to taste, do not season too sparingly, and simmer briefly until the coconut milk becomes thick. If necessary, the vegetable sauce can also be thickened with a little flour.
