I see nothing "unorganic" about
protein supplements as long as they are all protein. These are made by filtering by molecular weight (lactose, fat and protein all have different molecular weights). No fancy brands just plain protein. I use NO other supplements but whey isolate and a multivitamin. The rest of the diet is whole foods.
I rarely eat bars - I can't stomach
whey concentrate or casien so that elimates most of them. I do have some nut bars for emergencies.
Like Welch says - plan ahead and cook your meals in advance. You will be happier you did.
