50 gr Butter
50 gr Grated Parmigiano-Reggiano cheese
50 gr Pecorino cheese
50 gr Provolone cheese
Salt and Pepper
Select medium-sized courgettes (all the same size if possible), cut off the ends of each one and wash. Cut them in half length-wise and gently scoop out some of the pulp.
In a bowl, lightly mix together the butter with the grated Parmigiano-Reggiano and Pecorino cheese; dice the Provolone.
Spread a layer of the cheese and butter mixture on each courgette and sprinkle the diced Provolone on top.
Arrange the courgettes in rows in an oven dish and place in the oven.
