Cheap healthy delicious recipes?

Options
Hey everybody, I'm currently unemployed, my hubby has a job, but doesn't make much. We don't really keep much of the normal stuff people have in their kitchens... and he has to bring groceries home on a bike, so small amounts at a time. I'm not complaining, just explaining the situation...

Anyone have any recipes that are cheap to make, have few ingredients, are low in calories and carbs, as well as delicious?
