DIRECTIONS
In a large mixing bowl, beat the cream cheese, mayonnaise and mustard until smooth. Stir in the corned beef, onion, dill and salt. Using a 2-in. shamrock cookie cutter, cut out two shamrocks from each slice of bread.
Spread 1-2 tablespoonfuls of filling on the bottoms of half of the shamrocks; top with remaining shamrocks. Garnish with dill if desired. Yield: about 16 sandwiches.
