Are pepperoni Combos halal?

I'm curious to know, when it comes to the question of whether pepperoni combos are halal, what are the main considerations that need to be taken into account? Is it the ingredients used in the pepperoni itself, or perhaps the way in which the combo is prepared and served? Are there any specific rules or regulations in Islamic law that govern the consumption of pepperoni combos, and if so, how do they apply to this particular food item? I'm interested in hearing a comprehensive explanation of the factors that determine whether or not pepperoni combos are considered halal.
