I don't know that much about Egyptian cuisine, although I've heard of ful medames (I don't know if I spelled that right- and although it's vegetarian, I can't remember if it's vegan... I think it has egg in it? But if you made it yourself, of course you could leave the egg out.
You're right about good food being expensive sometimes- it's the same way where I am. Are you in an area where a garden would be possible? Even if you only have a patio with no soil, you might be able to grow some things in containers; the only thing about plants in containers is that they dry out faster than they would in the ground, and you have to be more careful about watering. If there's no place at all for a garden where you live, I don't know if they have community gardens in Egypt. If you've never gardened before, you could start small, with just a few plants that you know you like to eat.
I eat a lot of rice, pasta, and bread, and they can get boring. The legumes and vegetables I eat with the rice and bread make things more interesting, as well as being nutritious.
I wish I could be more helpful, but I don't really know that much about your area.
EDITED TO ADD: We have a group of forums for VB

In that same section of VB
