Prep the ingredients per the instructions above.
Make the marinade: Mix the marinade ingredients in a bowl big enough to hold the beef. Add the beef and mix well. Use your hands to massage everything together. Set aside for 30 minutes, or longer if desired.
Make the rice: Rinse the rice under cold water. Cook the rice according to the directions on the package.
Heat a large skillet or non-stick pan over medium-high heat.
Remove the beef from the marinade, reserving the marinade.
Strain the marinade into a saucepan over medium heat and bring to a simmer. Slowly stir the dissolved cornstarch into the marinade a little at a time (you may not need it all) until the marinade thickens to a smooth consistency, then remove and set aside.
Add the oil to the heated skillet or pan and sauté the onions for 2-3 minutes. Your pan should be hot enough so that the meat sizzles as it touches the pan. Add the beef (in batches if needed) and pan-fry/stir-fry the meat until slightly brown on both sides. Don't put too much meat into the pan or you will end up with a lot of the meat juice leaking out.
Pour the thickened marinade into the pan with the beef and set aside until you are ready to serve.
In a mixing bowl, combine softened cream cheese, finely chopped imitation crab meat, chopped scallions, minced garlic, and soy sauce. Mix until well combined.
Place a spoonful of the cream cheese mixture in the center of each wonton wrapper.
Moisten the edges of the wrapper with water and fold in half to create a triangle. Press to seal.
Heat vegetable oil in a pot or deep fryer to 350°F (175°C).
Fry the crab rangoon in batches until golden brown, about 2-3 minutes per side. Drain on paper towels.
Finish the rice: Once tender, season with salt and pepper to taste. Cover with a lid to keep warm until serving.
To the bowl of a blender, add the milk, matcha powder, and honey. Blend for 30 seconds to 1 minute or until the matcha is lump-free. Pour into glasses of ice.
Serve the bulgogi with rice, crab rangoon, kimchi, and matcha latte.
