Combine chives, lemon zest, flour, salt and pepper, and toss
the scallops in this mixture to coat lightly. With a round
cookie cutter (5-6cm), cut rounds from rye bread. Heat olive
oil in frying pan. When hot, add the scallops and brown
lightly. Remove and place each scallop on a round of bread.
To serve, drizzle a little lemon juice, then top with finely
chopped chives. Serve warm.
