What two animal proteins are found in the Mac + Cheese x2?

The correct answer highlights that Mac + Cheese x2 features both bacon and chicken as its animal protein components. This dish typically combines the classic comfort of macaroni and cheese with the savory flavors of these proteins, adding a rich and smoky element from the bacon alongside the tender, juicy notes of the chicken. Both ingredients complement the creamy cheese sauce well, enhancing the overall taste experience.

The other options do not apply because they either include protein types that are not part of the recipe or do not align with common ingredients used in this specific dish. For example, chicken and beef, pork and lamb, and fish and shrimp are combinations that are less typical in a macaroni and cheese preparation and are not included in the Mac + Cheese x2 dish specifically. Choosing bacon and chicken accurately represents the intended flavor combination found in this menu item.
