Welcome Rudderbird!
Back on the topic of Udis. We will not get into why I eat it, as I have no diagnosed allergy to wheat.
That is true, but I sometimes use Udis or Schaar products. My comments only relate to my impression of the quality and taste of the products I have tried.
I have had Udis a few times now. One loaf came on the shelf, and is sold at Trader Joe's. It was okay. Not wheat bread, but could be used out of the bag when first opened. As they go stale very quickly, I tend to toast to freshen. Just lightly. This works for me. I only tried a mulitgrain loaf and a white sandwich loaf.
I tried Schaar, and the loaf was all borken and so hard, and *had* to be toasted to be pallatable. Lightly so, to soften the bread again, not toasted hard. I did contact them about the quality, due to the borken pieces of more than half the loaf, rendering it useless for sandwiches. They were very responsive and sent coupons, so I will use those(one is for $6.50) and give it another chance. I think I liked the taste better, but not texture. But similar, really.
So, I think side by side, I would choose the udis non-frozen shelf product i got at Trader Joe's, since it was good right out fo the bag for a couple of days. Sometimes, I just like an egg salad sandwich on soft(ish) bread.
I hope that helps you! Welcome and glad to see your current food plan has you feeling so much better!
