For all you cheese addicts our there, like myself, here is a delicious Cheese'centric take on shepherd's/cottage pie. Honestly it can be made with just about any cheese, I am lucky though, my Ovo-Lacto Vegetarian friend is as insane about blue cheese as I am. I choose Stilton, rather than Gorgonzola, Maytag or Saga because I think it stands up better to the amount of onion in the pie. Honestly, I have never tried it with Roqueforte. The measurement on the casserole dish is in Liters because I have old Corningware (the original PyroCeram stuff.) All the sizes are marked in liters instead of quarts. For anyone with the Pyrex standard sizes the dimensions of my casserole dish are 10 long 7 wide and 3 deep so a Pyrex 11 x 7 should work for this, but your pie will not be as thick because that dish is only 1 1/2 inches deep.
