Is sheep cheese available where you live? I know I’ve seen Manchego in several US locations, but you have to check that it is real manchego, not “manchego style made from cow’s milk.” Other kinds (Ronkari or Roncal, Idiazabal) are rarer and tend to be more expensive but I’ve seen them too.
Olive oil is more expensive than other kinds but one of its advantages is that it can be reusable: you can use the oil you’ve used to fry veal to make a stock, you can fry a couple of leaves of lettuce in oil used to fry fish to get rid of the fishy smell and use it to fry something else, you can use the same pan of oil to fry a dozen eggs one after another. Most people in Spain, Italy and Greece don’t use dressings for salads (lettuce, tomato, hard-boiled egg, canned tuna are popular ingredients), we sprinkle a bit of salt, pour a twirl of olive oil, a tiny twirl of wine vinegar and stir it well.
