This is an absolutely ingenious way of doing two things. Firstly, I traditionally do not like having more bread than sandwich, which is why I often don't purchase whole wheat buns because they are actually larger than hamburgers and sliced veggie-meat. Size here is perfect. Secondly, I love opportunities to reuse items. This round bread recycles cans.

My mother became a vegetarian the day after Thanksgiving when she was 21. It is much easier to be a vegetarian today than it was even 15 years ago. Thanksgiving meals can be quickly prepared with meatless substitutes that taste as good as the real thing. (Obviously, this idea is subject to personal opinion. After all, I've tried meat and don't like the taste of it. I can palate soy meats much easier.)
