well most defendantly a taco would win in a fight like that, because a taco has mega spicy goodness that burns the grilling cheese sandwich. (but if instead of a cheese sandwich it was a baconator... things might go different.
Guys come on it doesn't matter what is about in this forum, it's just fun to think about what would happen.
Probably the grilled cheese sandwich...Well, mine would at least. I season my grilled cheese with some pepper and I put bacon chips in it; quite a feast I tell ya. You can put the pepper inside with the cheese or directly on the bread while baking it, either way, it's delicious; real novelty for the grilled cheese lovers.

^ You people should conveniently ignore that.
I like tacos, but I think if I took a taco in one hand, and a grilled cheese sandwich in another, and started bashing them together, I think the taco would fall apart first.
