You are talking about waterless hot pot! Wash all the vegetables and meat you want to fry, cut them into pieces, then put them all in the pot without adding anything, cover the pot, light them (remember it's a small fire, don't worry about dry burning, the sticky water is enough when washing the meat and vegetables), wait for the steam to come up slowly, turn to a small fire, and wait for more than ten minutes. It takes half an hour for the whole process to be fully cooked. Don't lift the lid halfway. When cooked, take out the contents of the pot, put salt in the salt and seasoning in the seasoning, and serve.
