Crush the garlic using the flat side of a knife, then mince it finely and set aside.
Cut the green onions into ¼-inch pieces.
Julienne the butternut squash into 2-inch-long, 1/4-inch-wide pieces.
Heat oil in a wok or skillet over medium heat.
Throw in the minced garlic and fry until golden.
Add the ground pork to the frying pan and stir.
Add MSG, sugar, fish sauce, and oyster sauce, then stir everything together in the pan.
Add the julienned butternut squash when the pork looks cooked.
Continue frying for 7 minutes (or until the squash becomes noticeably soft) while stirring the ingredients continuously. Then, remove from heat and serve.
