Separate
the chicory leaves and wash and dry them carefully.
Arrange them, rounded-side down, on a large serving
platter.
Heat
1 tablespoon of the oil in a nonstick frying pan,
add the pancetta and cook over a low heat until the fat runs.
Increase the
heat to moderate and cook, stirring constantly,
until the pancetta begins to color and crisp.
Remove the pan from the heat and, using a slotted
spoon, transfer the pancetta to kitchen paper to
drain.
Sprinkle the pancetta inside the chicory leaves,
then sprinkle over the pecorino and pepper to taste.
Add the remaining oil and the lemon juice to the pan
juices and return the pan to a medium heat. Stir
until sizzling, then drizzle over the chicory and
serve immediately.
