1. A food product comprising:
a first extruded component;
a second extruded component encapsulated completely by the first extruded component, the second extruded component comprising one or more of a vegetable, a fruit, dairy, starch, and a secondary protein, the first extruded component and the second extruded component being distinct; and
a first extruded collagen layer surrounding the first extruded component and the second extruded component;
wherein a cross-section of the food product has a substantially constant outer diameter and varies along a longitudinal axis of the food product such that a first cross-section at a first axial location comprises a section of the first extruded component, but not any of the second extruded component, a second cross-section at a second axial location comprises a section of the first extruded component circumferentially surrounding a section of the second extruded component, a third cross-section at a third axial location comprises a section of the first extruded component, but not any of the second extruded component, and a fourth cross-section at a fourth axial location comprises a section of the first extruded component circumferentially surrounding a section of the second extruded component;
the second axial location being disposed between the first and third axial locations, and the third axial location located between the second and fourth axial locations, each of the cross-sections being defined in a plane normal to the longitudinal axis of the food product.
