Heat a large wok or skillet over medium-high heat.
Add the cooking oil and sesame oil.
Once hot, add the garlic and ginger. Stir-fry for about 30 seconds, just until fragrant. Be careful not to let the garlic brown.
Push the aromatics to one side of the pan and pour in the beaten eggs. Scramble until they’re just set.
Add the cold cooked rice, breaking up any clumps with your spatula.
Pour in the tamari and fish sauce, then continue stir-frying for 2 to 3 minutes until the rice is evenly coated and heated through.
Season with white pepper and stir in the green onions.
Serve immediately.
