Make the beef: In a food processor or blender, add the onions, pear and ginger. Puree finely. Pour into a large bowl, add the remaining ingredients and stir.

In a large saute pan, add the oil and the beef. Break up the beef and cook until browned. Add the soy/onion/pear mixture and mix well. Cook until all the liquid has evaporated.

Preheat the broiler to high.

On a sheet pan, layer the tortilla chips, beef, kimchi and cheese. Stick the pan under the broiler and cook about 5 minutes, keeping an eye on it to make sure it doesn't burn. Cook until all the cheese is melted.

Garnish with the sliced green onions and serve!
