"seems a bit wasteful of oil to cook them in loads of oil, then straining them"
As I pointed out in a recent comment, olive oil can be reused several times as long as you don't overheat it, filter it immediately and keep it in a closed container after use. The only problem is that some flavours will remain in the oil, but you can reuse the oil from a tortilla española for making another tortilla, or for frying meat, to which it gives a nice taste.
