Thaw the puff pastry (if frozen) about
15-120 minutes).
Preheat the oven to 200° (use hot air).
Filling
Remove the stones from the olives.
Grate the cheese (finely).
Rinse and pat dry the herbs and remove the stalks.
Blend everything (but the pastry), adding oil until mash,
but still quite firm
Taste to season with pepper, and salt if needed (careful
here…)
Making the rolls
Divide the pastry into 4 pieces, each about 175 g. For each
of them:
Roll it to a very thin 15-20 x 40 cm rectangle, between
two sheets of baking paper
Spread ¼ of the paste, and roll the sheets (from the long
end, so the roll will not be too thick).
(If possible, wrap in plastic and freeze for 20-30
minutes now to make it easier to slice)
Cut the roll in ½-1 cm slices and put the slices on
baking paper on baking trays. (Don’t worry if they are a little flat after
slicing, they will be fine when baked).
Bake
Bake for 12-15 minutes in 200° until they are golden/slightly
dark – keep an eye on them.
Chill for 5 minutes on a grate and serve
NOTE You may prepare the (unbaked) rolls in advance
and store them in a freezer for several weeks (or a week in the refrigerator).
If frozen, unthaw for an hour before slicing.
