Combine chocolate coating and shortening in a large microwave-safe bowl; cover loosely with heavy-duty plastic wrap. Microwave at HIGH 1 1/2 minutes or until melted, stirring once. Stir in peanut butter. Let stand 2 minutes. Stir in granola bars, sesame sticks, and almonds. Stir in marshmallows and caramels last so they don't melt. Drop by rounded tablespoonfuls onto parchment or wax paper. Let clusters stand until firm.
