Slice a large mild onion and fry in olive oil until its translucent and soft. Put the cooked onion and some of the oil it cooked in into a food processor and whizz it until its an off-white paste. Put on one side.
Slice a medium pork tenderloin into medallions about between 5mm and 1cm thick. Dip them in oil, then in a flour herb mix, coating them thoroughly.
Fry them in a little very hot olive oil for a couple of minutes each side. Hot enough and fast enough that the herby flour absorbs all the oil and goes brown and crispy. The turn the heat down just a little and add a smear more oil and half a jar of colmans apple sauce (or any other smooth apple sauce - avoid the asda one, as it has lumps in) and the onion paste you made earlier. If it feels a little thick, add either some water, or a little white wine to loosen the sauce. Cook until the sauce is heated through, and serve with saute potatoes.
My mouth is watering reading this! It's on next week's list ;-)
