Cook the mungo beans first. Add mung beans to a saucepan with 1-1/2 cup water and boil for 15-20 minutes or until tender. Drain any remaining water and set aside.
Meanwhile mung beans are cooking start preparing stir-fry. In a frying pan heat up olive oil. Add onion and garlic. Sauteé for 2 minutes. Add all the remaining ingredients to make stir-fry and cook for another 10 minutes over medium to low heat. Stir occasionally. Turn off the heat.
Prepare sauce for stir-fry. Mix all the ingredients and add cooked mung beans. Add the sauce to stir-fry and mix everything with a big wooden spoon.
If you serve stir-fry with rice noodles, cook noodles according to package instructions. Divide into bowls and mix with your mung beans stir-fry.
Enjoy!
