This is coming from a person who really doesn't like bread:
Have you checked out 'The Baker' brand? They're pretty hardcore wheat bread from Germany (obviously they have bakeries here too or else .. it would be moldy). No preservatives, no bleached flour, etc etc (so eat it fast or keep it in the fridge). They make a lot of varieties.

Personally, I like Ezekiel bread, it's sprouted wheat/spelt/oat/lentil/etc so it's flourless. Since it's sprouted, it's more nutrient dense than flour-type bread. So you get a lot of B vitamins and Iron out of it (not added in like the flour breads) and another point to mention is sprouted grain bread doesn't spike your blood sugar so it has a low G.I. index (don't know if that appeals to you or not, but it does to me). It also tastes pretty good..looks like regular bread. They also make slammin' english muffins. Keep 'em in the fridge or freezer though.

Oh, The Baker brand makes a sprouted grain bread that's really dense, nutty, chewy and moist. But it's flourless and looks kinda strange. It falls apart kind of easy too but it's goooood.

Health food stores tend to carry both those brands I mentioned. I hope you can find any of those in TX.
