Boil the pasta in plenty of salted water, drain when al dente and rinse under cold water to cool.
Slice the courgettes with the mandoline and grill on a hot grill for a few minutes, then cut into thin strips.
In a bowl, place the tomatoes cut into wedges, the fresh baby peas, the chopped anchovy fillets, grilled courgettes, the pasta, basil leaves and shavings of Grana Padano. Mix well, season with salt and pepper and add a drizzle of olive oil.
Serve the pasta salad chilled.
