Why don't people want to eat lentils? I'm pretty lazy, and I make lentils with chorizo, potatoes, onion, carrot and a mix of vegetables and some condiments all the time. It's very easy to make, cheap and tastes fantastic with very little effort.
Same with rice. It takes a little bit more to master rice, but lentils man it's the lazy meal for me. I also buy frozen vegetables that lasts who knows how much, and it tastes as good as with fresh ones.
Most of spanish cuisine is cheap and more or less easy to make. I'm not really sure that processed food is cheaper. A pot of (again) lentils can last a bunch of days and costs nothing.
