... Why would you cheat? Celiacs is a serious disease, and can lead to additional immune system problems. There are so many gluten free options that are delicious and healthy, why feel the need to eat wheat? Even if your noticed response is mild, your insides are under attack. I too am curious as to why you have gotten 3 endoscopies in a year, that seems excessive imo. Of course, it's your body and your life but if I was in your shoes I would stick to a gluten free lifestyle and let my body heal. Celiacs is not something to mess around with, and even if your symptoms are mild now they may be much worse in the future. 

Breyers has been great for me, Talenti was one of my favorites before I found out I was allergic to wheat. Haven't tried any of their flavors yet, but their website lists a ton of delicious gluten free flavors.

I would steer clear personally, CC risk is going to high there, you have teenagers preparing the food that aren't paid enough to care. I wrote off fast food after learning I was allergic to gluten, the cantina bowls are healthier but it's still fast food. My homemade tacos are much tastier and contaminate free.

Your TSH levels are in the "normal" range, which is anything between 0.4-5. Everyone's "normal" for TSH varies but it seems your thyroid is functioning as it should. I was diagnosed with Hashimoto's Hypothyroid for about 4 years now and your symptoms do mirror some of the classic thyroid symptoms but not in a way that I would definitely say it's your thyroid. Going completely gluten free sounds like your best bet, give it some time to let your insides adjust and re-evaluate. Trial and error sucks, especially when it concerns your health.
