First boil the macaroni in a small bowl with a litte water.
Allow it to cook in the microwave for 3 to 4 minutes till it is al dente.
Throw the water out or squeeze the water out of the macaroni and put it in a bowl.
Now add channa dal, rice flour, salt, chilli powder, onion and mix all together till it forms a coarse dough.
Try not to add water; you can wet your hands in the cooked macaroni water, which is a little thick because of the carb content in the macaroni.
Taste test the dough for salt and chilli.
Pour oil in a deep kadai and let it become hot, and when it is very hot, reduce the heat of the stove, and start putting small balls of dough or push a small amount of dough between your thumb and index finger.
You can put 5 to 6 balls and start frying.
When it turns color and becomes light brown, you can take it out and place it on a paper towel, so that the excess oil is absorbed.
The same way finish the remaining dough and serve it with tomato ketchup or mint or coriander chutney.
