how am I supposed to cook anything in this temperatures?

I still haven't had any dinner, because it's clear that the Spanish custom to have dinner really late around ten or so in the evening, is the only sensible one in this this kind of heat. Any earlier is simply too hot to have any substantial appetite.

And this awful weather sucks for my food budget. In reaction to the intolerable temperatures I'm mostly subsisting on chilled yogurt and fruit and the like, which I'm sure is healthy and everything, but even in season fruits are expensive. Also, ultimately while tasty not all that satisfying.

I'm hungry, I have plenty of food at home, but I'm too sticky and lethargic to cook myself anything.
