I used to order sausages and schnitzel from them but a year or so ago their prices jumped and I've not had anything since.
Lidl do a decent two pack of schnitzel which is now my first choice.
Really GOOD schnitzel are *so* easy to make. They're regular menu items here chez Casa Reynard, and far better than anything you can buy.
The very easiest are the turkey ones. I use the packs of thinly-sliced turkey breast, no need for any other prep. Otherwise, I use pork steaks (loin or shoulder), and bash the living daylights out of them with a meat tenderizer until they're about breakfast plate sized.
Then, you'll need two large flat dishes - one with a couple of beaten eggs in (good for three to four schnitzel), and another with well-seasoned breadcrumbs*. You can choose your seasonings, but a mix of salt, pepper, thyme and smoked paprika is good.
Dip your meat in the egg and then into the breadcrumbs to coat. The repeat. US-stylee double dipping will give you a nice crunchy crust.
Shallow fry in hot oil until golden on both sides.
I make my own breadcrumbs using yellow sticker hot dog rolls. I break them up, dry them out in the oven, then toast them lightly before whizzing them up in a food processor.
