Corn is very high on the glycemic index. There is a reason they make HFCS out of it. Most dietitians don't even really consider it a vegetable but more of a grain.I agree. My youngest made it once, she ate a few pieces and said it wasn't bad, but she'd made wayyyy too much and didn't eat it all. I have a friend who has a wheat allergy so she is always trying to find new and edible ideas for stuff, but she hates mushrooms. I would probably do the mushroom bun thing too! It sounds really good. What about corn tortillas? When my youngest was seeing a nutritionist they suggested using tortillas instead of bread to cut down on carbs. Not sure if corn tortillas would be any safer for you than the wheat ones though.
