Staple items that go far? So i'm getting ready to move out and pay for all my groceries so I need to get ready to be frugal with grocery money. 

What are staple items that are cheap and go in many meals? 

I know rice and beans are popular on here, but I struggle to make a rice based dish that isn't stir fry or chicken fried rice. 

Any other suggestions? or suggestions that don't require a meat with them all the time?
