Frozen bagels can be too bready whether they are gluten free or non-gluten free. I love O’Doughs Bagels. Of all the gf bagels that I have tried, O’Doughs bagels have the texture most similar to a non-gf bagel. And they are thinner, so they aren’t too filling. I’ve tried their sandwich thins which are also very good. They have many products that I haven’t found in any of my local stores, but you can order from their website. It appears they use a gluten free distributor as an e-commerce source.
