Using a food processor, finely chop chicken (or shred using 2 forks). Place in 1 quart bowl and set aside.
In a small bowl, stir together mayonnaise, curry, coriander, salt and pepper.
Stir curry mixture into the chicken until completely combined. If too dry, add another teaspoon of mayo. You want it to hold together without excess mayo oozing out.
Using a 1-1/2 inch biscuit cutter (or a small jar), cut out 4 rounds from each bread slice. Arrange on serving platter in a single layer.
Place a rounded tablespoon of chicken mixture on each slice. Top each with a 1/4 teaspoon of chutney, then gently press in a pecan half.
If not serving within an hour, cover with plastic wrap and refrigerate. Remove from fridge about a half-hour before serving.
