You may need to add some extra water if you put pasta in. Great served with crusty wholemeal bread. Asafoetida powder is an alternative to using onions, it can be found in good deli's and health food stores, but beware, it has a very strong smell and needs to be stored in an airtight container.
Since I am not a sentient vegetarian, I did use onion and garlic instead of the asafoetida powder. Quite tasty added lots of salt and pepper for my tastes - 28 Oct 2013
