In a large skillet, heat oil over medium-high heat. Pour eggs into skillet. As eggs set, lift edges, letting uncooked portion flow underneath. When eggs are completely cooked, remove to plate. Set aside.
In the same skillet, combine the rice, pork, peas, soy sauce and garlic powder; heat through. Meanwhile, chop egg into small pieces; add to skillet. Remove from the heat; stir in lettuce and onions. Serve immediately.
