Place frying pan on medium-high heat. Place oil in. Once hot, add onions. Stir-fry until onions turn translucent.
Then add beef slices one-by-one into the frying pan. Separate each piece so that they don't clump with each other.
Once the beef loses most of its red color, add in the sliced Carrots and Mushrooms. Stir-around for 30 seconds.
Next, add water (1/3 cup) to the stir-fry. Stir-around.
Then add in the rice cakes.
Add Oyster Sauce (1T), Soy Sauce (1T), Sugar (1T) and Honey (1T) to the mixture. Stir-fry everything together.
Now, add Bell Pepper and Spring Onion pieces to the stir-fry.
Once the Bell Peppers get soft, turn off the heat.
Garnish with Sesame Oil (1T) and give one last stir. And top-off with Sesame Seeds (few shakes).
