This recipe adds a refreshing twist to the classic Sarde a Beccafico by incorporating lemon and mint into the stuffing for the sardines. The lemon adds a bright and tangy flavor, while the mint provides a fresh note. The sardines are stuffed with a mixture of breadcrumbs, lemon zest, mint, pine nuts, raisins, and olive oil. The dish is then baked until the sardines are crispy and the stuffing is golden brown.
