I don't normally find canned foods to be terribly appetizing, but I bought a couple of cans of Jyoti brand dishes at The Cupboard in Denton (organic greenie tree-hugger grocery store) and I have to say that this stuff was GOOOOOD!
In particular, I found the Dal Makhani to be quite tasty. It reminded me a little of Mexican refried beans, only with a serious Indian twist. I did a distinctly un-Indian thing and mixed in some chopped brisket, and it was grrreat. I may have to order some of this online. Today I'm having some peas with paneer cheese and it's also very yummy.
