If you haven't already cooked your rice, do so according to package instructions.
For best results, use rice that has been cooked and chilled in the refrigerator for at least a few hours or overnight.
Heat 1 tablespoon of vegetable oil in a large skillet or wok over medium-high heat.
Add the minced garlic and diced onion, and sauté until fragrant and the onions are translucent, about 2-3 minutes.
Add the mixed vegetables to the skillet and cook until they are tender, about 3-4 minutes. You can use fresh or frozen vegetables for this step.
Push the vegetables to one side of the skillet, and pour the beaten eggs into the other side.
Allow the eggs to cook for a minute or two, then scramble them with a spatula until they are fully cooked.
