Heat a little oil in a frying pan on medium heat. Saute the garlic and grated ginger just until aromatic (less than a minute). Add the ground pork and brown in the pan.
When the meat has changed its color add the onions. Cook for another 3-4 minutes or until the chopped onions have softened. Add the carrots and season with the soy sauce.
Prepare the spring roll wrappers and have a small bowl filled water near you. Place about 1 heaping tablespoon of the cold pork mixture in one of the corners of the wrapper.
