Do you like spicy food? You can make approximations of lots of curries in a single pot and they're very easy to adjust to your own taste. Obviously the ones with cream/coconut cream sauces are pretty calorific, but you can make low fat substitutions or reduce the amount of sauce you make.
I love tarka dal (daal/ dhal), which also has the advantages of being incredibly cheap to make and a great comfort food. Just serve your choice of flat bread or, as I have been known to do, just a spoon. There are endless of variations of dhal and I would suggest doing a bit of googling to find one that you fancy.
Still on the subject of spicy - I make aloo gobi (potato and cauliflower curry) a lot. It doesn't need anything else to go with it because of the potatoes.
Oh, and I was having a look for other suggestions for you and came across this www.bbcgoodfood.com/recipes/10052/spring-c
No idea what it's like, but I'll be trying it for my dinner at some point this week.
Any of those any good for you?
