Hm, this would make more sense if there were only 2 buns... lettuce can be a bit difficult on burgers, so to have the lettuce in a burger shape might make it easier, but it needs to go on the same bun as the meat.

But, it also needs to be clean veggies, not that vegan crap that gets added to vegan things, as we all learned about from Saifedean 😇😎
