Sardines are in season from spring until early autumn so enjoy them at their best, stuffed with herby breadcrumbs and creamy feta cheese.
To remove the backbone from the sardines, simply place the fish on a board, skin side up, then press down along the length of the bone to loosen it. Turn fish over, snip the bone at the tail end and tease it out, removing any small stray bones with a pair of kitchen tweezers.
