To start, slice the Ribeye into 1/4 inch strips, against the grain
Place meat into a bowl and add the grated pear, minced garlic, sesame oil, soy sauce, brown sugar, gochujang, and grated ginger.
Coat the meat and mix well, cover, and refrigerate for a minimum of 4 hours, ideally overnight. Stir the marinade over from time to time.
Before you're ready to start cooking, remove the marinating meat from the refrigerator and bring to room temperature.
In a sautee pan, or wok, bring the pan to high heat and add the vegetable oil
Add a third of the meat to the pan, being careful to not overcrowd it.
Cook for 6-8 minutes, until cooked through. The bulgogi will be done when the edges of meat start to brown and caramelize.
Continue cooking until the batch is finished.
Serve over rice and garnish with a sprinkle of sesame seeds and slices green onion.
