Agree - that picture looks nothing like any chilli (or chili) I've ever seen, looks like a mound of grated cheese
On 2 there is confusion about chilli/chili in the article which says that
A chilli is a hot pepper but also says that
Chili is a spicy stew made with chili peppers, garlic, cumin, garlic, onions, and ground beef. I don't think there can properly be a difference in the spelling of the dish and the pepper because the proper name of the dish, as I understand it, is
chilli-con-carne, i.e. chilli with meat. So however you spell the name of the pepper should also be the way you spell the first part of the name of the dish.
