Urgh !
I use Olive oil to season salads, or pour it in soups or minestrone to add extra flavour.
Also, I sometimes just pour some of it on a plate, and collect it using pieces of bread as a sponge, like you would do with the sauce left in the plate after eating a pasta.
My Dad used to make for himself a lovely snack: a slice of nice bread, spread some sugar on it, then pour a film of olive oil. I suppose being sugary does not really belong to the sort of diet recommended here, but I thought I would mention it.
I exclusively use extra virgin olive oil, which in this part of the world means the oil obtained from the first press. Hope this helps,
