Heat a small frying pan over medium heat, and add the oil. Then add the chopped garlic and green onions and stir/cook for 30 seconds or until they become aromatic.
Remove the pan from the heat and add the powdered ingredients. Stir well to combine, then set aside to cool.
Once cooled, add the sour cream to the onion and garlic mixture and stir very well to combine. The dip is ready to eat immediately, but it’ll taste even better after 20-30 minutes in the fridge.
