I think you are being very naive bkgirl.
Afghanistan is a country which hasn't been able to be governed effectively...well ever. Russia tried it for over a decade. Now we're there fighting a losing battle.
There's barely any infrastructure, literacy is minimal and the only thing the people seem to know how to do is fight. Corruption is rife and endemic. Women are second class citizens which can be sold and if raped are the ones to be thrown in prison.
It's also a huge country which despite the huge numbers of soldiers we've sent over there, the billions we've spent 'pacifying' the Taliban, it isn't nearly enough to form stable security.
In that context just how do you propose we feed everyone? It's not a case of not buying a bomb and delivering a food parcel. If only it were that easy.
We'd have to send over hundreds of thousands more troops, all heavily armed to ensure food aid is secured, delivered and didn't just disappear. That will mean shooting more locals and more of our troops returning maimed or in body bags.
So in short, the only way to achieve what you want is to actually send over more bullets and bombs.
