Heat oven to 400 degrees. Lightly brush botrh sides of bread slices with melted butter. Place in single layer on baking sheet. Bake in 400 degree oven for 8 minutes or until the bread slices turn golden brown, turning each slice over after the first 4 minutes. Stir together honey mustard and sour cream in a small bowl. Brush one side of each piece of toast with honey-mustard mixture. Arrange toast pieces, mustard side up, on serving platter. Carefully select blemish-free inner leaves from the heads of Bibb lettuce. (Reserve remainder of heads for salad.) Trim leaves so they fit neatly on top of bread slices. Place 1 leaf on each bread slice. Cut salmon into 2 1/2 x 1 inch strips. Roll up each strip loosely and shape to form rose. Place 1 rose on each lettuce leaf. Garnish with dill.
