Crack the 2 eggs into a small bowl and whisk them together with a fork until the yolk and whites combine completely. Heat 1 tablespoon of vegetable oil in a large skillet or wok over medium-high heat for about 1 minute until it shimmers. Pour the eggs in and scramble them quickly, breaking them into small pieces as they cook. Transfer the cooked eggs to a separate plate — they'll keep cooking in the pan later, so pull them out when they're still slightly soft.
Add the remaining 1 tablespoon of oil to the same skillet and wait for it to heat up again. Add your diced chicken breast and cook it until the outside turns golden and it's cooked through, which takes about 5-7 minutes depending on your heat level. You'll know it's done when there's no pink inside and it's no longer jiggly. Stir it occasionally so it cooks evenly.
Push the chicken to one side of the skillet and toss in the minced garlic, ginger, and onion all at once. Let them sit for about 30 seconds before mixing everything together — you'll hear it sizzle and smell that amazing fragrance. Cook for 2-3 minutes until the onion starts to soften and the garlic loses that raw bite. This is where the flavor magic actually happens.
Add the carrots and peas to the pan and stir everything together for about 2 minutes. These veggies cook super fast since they're already pretty soft from being frozen or pre-cut. You want them warm and mixed in, not mushy, so don't leave them sitting in the pan too long.
Dump in all 2 cups of your cold cooked rice and break up any clumps with your spatula or wooden spoon as you stir. Keep moving everything around for 3-4 minutes so the rice gets coated with the oil and mixes with all those flavors you just built. The rice should start looking drier and more separated as it heats through. This is the key moment where fried rice actually starts tasting like fried rice.
Pour the soy sauce over everything and toss it all together for another minute so the soy sauce coats every grain. Add the salt and black pepper and taste it right from the pan — honestly, this is the best part because you can adjust the seasoning exactly how you like it. If it needs more salt, add a little pinch. If it's too salty, you're out of luck, so go easy here.
Add those eggs back into the pan and fold them in gently so they break into even smaller pieces throughout the rice. Everything should look golden and mixed together now, with no white rice showing through. Serve it immediately while it's hot, or let it cool and store it for later.
