Since being diagnosed with Celiac disease the adjustment has been pretty easy to make. Most of the foods I eat are naturally gluten free anyway and when I crave things like cereal or bread there are plenty of gluten free replacements available.
Every once in a while though I do get a twinge of jealously when I see a really awesome recipe using regular flour or other gluten contaminated ingredients. I recently saw a recipe for homemade blondies and thought they sounded amazing. I got inspired to make my own Paleo and gluten free version that would hopefully be just as good. Now I can't promise these are any comparison to the original but they did get my gluten-eating sister stamp of approval!
