Staying full on a limited budget?

When I was broke, my staples tended to be:

- dried beans in bulk
- brown rice in bulk
- potatoes
- oats in bulk
- whole grain sandwich bread (nothing fancy, but I preferred whole grain and have never liked cheap white bread)
- peanut butter
- cabbage...lots of cabbage
- frozen vegetables when on sale
- whatever the cheapest apples were
- whatever meat/poultry was on sale...usually lots of chicken parts and whole chickens
- eggs

For you breakfast, I'd personally ditch the bread and opt for oats or something...more filling and more nutrition and dirt cheap.
