I am a BIG fan of red lentils. They can be prepared incredibly quick from dried. I cook them with garam masala then, when done, firmly press to cover the bottom of a lightly oiled pan and fry. It gives you an excellent crispy delicious crust for other goodies to be piled on.
Other things, among many, at Grace that make it worth the trip: their selection of spices; lime leaves; the packages of flat flexible sheets of dried mini-bananas (smeared thin with PB and rolled like a Piroulline cookie - very good); and their large tubs of tofu (12 blocks/tub for 2.99), great for miso soup.
And for comic relief: the refrigerated beverage section. Example: Mrs. French's Vanilla Corn Drink. (shudder)
But this was about beans: Grace is my pick.
p.s. they do have smaller bags (~400grams) of all the above as well (also cheap)
