Contrary to popular belief, chili con (or sans) carne, is not Mexican, but originated in the south-western states of the USA. It was invented by settlers on the trail, to places like Texas, New Mexico, Arizona and California.
The basic recipe for proper chili con (or sans) carne, is mince (the base ingredient can be as variable as availability allows), tomatoes (optional), chillies and onion, garlic was added only in the last hundred years or so; that is it.
Kidney beans can be served on the side. The inclusion of the beans in the main dish is a relatively new concept (early twentieth century and originated in Tex-Mex cuisine). Rice can also be served.
Spaghetti Bolognese is mince (as before, the base ingredient can be as variable as availability allows), pancetta, tomatoes, onion, (celery, optional) garlic, basil, oregano/thyme and olive oil (and of course spaghetti), Sangiovese wine is a useful addition (but any red wine will suffice). In Italy, especially in Bologna, it is not serve as a huge amount of sauce plonked on top of pasta, but is lightly incorporated onto the pasta, coating it, so all the pasta has sauce and some mince on it.
The best bolognese I have ever had was cooked by Gennaro Contaldo, back in the early eighties, when I used to eat at the Neal Street Restaurant.
