Heat the cannabis-infused olive oil in a large saucepan on low. Add the garlic and cook for two minutes, stirring. Add in the chili sauce, oyster sauce, pepper and salt and stir until mixed. Then add the spinach. Cook on one side for about five minutes and then use a spatula to flip the spinach over. Cook on the other side until the spinach becomes tender. Give one final stir before serving and enjoy! Serves four.
