Have you considered cooking up big batches of dishes and freezing them in containers big enough for one or two meals? Makes it so much easier when you're in a hurry for something to eat.
When purchasing bulk foods, especially beans, you may want to check with your store regarding the country of origin of the products. When I was in a food-buying club, a lot of the beans were coming from China. Not very sustainable, in terms of miles traveled, and also, perhaps less than organic, if that's what you're purchasing.
