Prepare all vegetables, seafood, sausages, tofu, and other ingredients by cutting them into bite-sized pieces.
Heat oil in a pan, then stir-fry garlic, dried chili peppers, and mala sauce until fragrant.
Add all the prepared ingredients to the pan and stir-fry over high heat.
Pour in heavy cream and milk, then mix well and simmer.
Once the ingredients are cooked through and the sauce thickens, transfer to a plate and serve.
