1 cup fresh lump crab meat, picked over
2/3 cup mayonnaise
2/3 cup freshly grated Parmesan cheese
4 green onions, chopped fine
1 teaspoon fresh lemon juice, or to taste
Salt and freshly ground pepper to taste
Preheat oven to 400 degrees. Toast bread on a baking sheet in oven until golden, about 5 minutes.
In a bowl stir together remaining ingredients with salt and pepper to taste. Reduce oven to 375 degrees.
Spread crab-meat mixture on toast triangles and arrange on baking sheet. (Canapés may be assembled 30 minutes in advance.) Bake canapés in middle of oven until puffed, about 10 minutes.
Makes 48 canapés.
