Beans, avocado, fruits, nuts, eggplant, spinach -- remember to take a fiber supplement.

You can do a lot of creative things with these kinds of food potentially.

In terms of delicious Indian foods, you can make Baingan bharta (roasted eggplant curry type dish), saag gobi tofu (spinach/cauliflower/tofu). You could make falafels and bake them to be healthier.

I don't really like spinach that much, so sometimes I make spinach smoothies to cheat. Basically, I just take a banana, strawberries, avocado, a little non-dairy milk and as much spinach as I want and blend it together and drink it. There's probably a way to make it better than what I do, but you can really cram a lot of spinach down your cram hole this way.
