Prepare the Ginger Soy Sauce : In a small bowl, whisk together soy sauce, rice vinegar, sesame oil, honey, ginger, and chili flakes. Set aside — this will be the flavor base for your fried rice.
Sauté the Aromatics : Heat oil in a large wok or skillet over medium-high heat. Add minced garlic, ginger, and diced onion. Sauté for 1–2 minutes until fragrant and slightly golden.
Add the Vegetables : Add carrots, broccoli, and mixed vegetables. Stir-fry for about 3–4 minutes until vegetables are tender-crisp. Season lightly with salt and pepper.
Add Rice and Sauce : Add the chilled, cooked rice to the wok. Break up any clumps with a spatula. Pour in the ginger soy sauce and toss to coat evenly. Stir-fry for 3–5 minutes, allowing the rice to absorb the sauce and slightly crisp up.
Optional Egg Addition : Push the rice to one side of the pan. Crack eggs on the empty side and scramble until just set. Mix eggs into the rice mixture.
Finish and Garnish : Add chopped green onions and toss everything together. Remove from heat, sprinkle with sesame seeds, and serve hot.
