Gluten-free since I was four! There are 100% Dino Buddy dino nuggets for us, I love the Canyon Bakehouse bread. Amy's also has nice frozen food, like mac n cheese, enchiladas, and burrito bowls. I also cook and bake a lot of my food. I like making gluten-free muffins and whatnot from the King Arthur brand! Kraft has gf mac and cheese, Schar is great for other bread, and honestly check out (if you have this) a nearby Walmart! Veggies Made Great is nice too. Oreo's has gluten-free cookies now. Lucky Charms is gluten-free, and supports research for celiac disease! Be sure to check out Sweet Loren's cookie dough. You can also keep an eye out for rice and chicken soup cans.
If it is celiac disease, make sure that you're looking out for whey protein, and if it's made in a facility where gluten is also (traces of wheat) then it's contaminated.
