An extrusion die assembly (10) for forming a food product having an elongated shell made of an extrudate includes a die housing (24) and a nozzle (22) disposed within the extruder housing (24) such that a passageway (30) is defined between the die housing (24) and the nozzle (22) for passing the extrudate. A removable die plate (26) having a die opening (54) is positioned across an outlet (32) of the die housing (24) such that an annulus (58) is formed between the nozzle (22) and the die plate (26) for passing the extrudate to form the elongated shell.
