In place of mini bagels, little toasts or sturdy crackers are good stand-ins to hold the crab spread.
Toast bagels lightly under the broiler for 1 to 2 minutes or until golden brown. Meanwhile, for spread, stir together the cream cheese, chili sauce, and horseradish in a mixing bowl until combined. Stir in crab. Transfer mixture to a serving bowl. Garnish with snipped chives or parsley. Serve crab mixture with toasted bagel halves.
Prepare spread; cover and chill up to 2 hours.
