Prepare rice according to package directions.
In large wok or skillet over medium-high heat, heat oil. Stir-fry mushrooms and onions 3-5 minutes, or until softened. Stir in kimchi, garlic and ginger; stir-fry 1-2 minutes, or until well coated.
Stir in rice, spinach, soy sauce and sesame oil. Stir-fry 2-3 minutes, or until spinach starts to wilt and rice is heated through.
Divide rice between four bowls and top each with one fried egg.
