To make the Mongolian sauce: You will put the sugar, soy sauce, and water in a pan. Leave the pan to heat on a medium-low flame. Stir occasionally to make sure all the sugar is dissolved.
When all the sugar is dissolved, add in the sesame seeds and oil, as well as the ginger and garlic.
Give it a good mix, then take it off the flame. You can store it in a container in the refrigerator if you want to make it in advance.
To prepare the Mongolian BBQ: start off by cooking the noodles until al dente, according to package instructions. Leave the noodles aside after sprinkling some oil to prevent it from sticking.
Start slicing your meat into thin 1/8-inch thick slices. Do the same for the vegetables after washing and drying the bean sprouts and removing the hardcore part of the cabbage.
Divide a preheated sprinkled with oil, griddle to 400 ºF (204 ºC) into sections. Add the meat and vegetables into separate sections.
Sprinkle salt and pepper on the vegetables to season them.
It should take few minutes to cook the meat. Leave the vegetables until they soften.
Serve the meat and vegetables with noodles in a bowl, together with the Mongolian sauce. Enjoy!
