Pigging out on prawns

Lidl supermarket had a special on today, 800 grams of prawns for 2.59 euros
couldnt resist them so have stocked up the fridge and freezer, so it will be prawns with salad, prawn cocktails and paella with loads of prawns, and you can save the shells and boil them up to make a nice fish stock.
I got to Lidl as they opened and the offer was soon taken with most people having 2 or 3 boxes each.
