Mix together the cream cheese and Stilton until well blended. Salt and pepper to taste. Spread the cheese mixture on each of the prosciutto slices. Brush the pear slices with lemon juice and place one slice on each slice of prosciutto. Roll up the prosciutto lengthwise. Wrap in plastic wrap and chill until ready to serve.
I think I'd skip the Stilton if using smoked salmon. This could also be made into a wrap using tortillas. I'm not sure about the pear. Maybe instead of the horseradish you could dice some canned pear and mix with the cream cheese? Btw, the notes aren't mine....we eat prosciutto frequently....Sam's sells it at a reasonable price.
Did you know you can toast it in the oven then crumble it as you would bacon? So good and so much lower fat!
