Heat a wok over medium-high heat. Add 2 tablespoons of cooking oil and wait until the oil is hot. Then, add the minced garlic to the wok and stir until it becomes fragrant.
Add water or stock until it reaches just halfway up the pumpkin, then add 2 tablespoons of salt. Quickly stir the ingredients and cover the wok with a lid. Let it simmer for 10-15 minutes, or until the pumpkins are soft and the liquid is reduced.
