A method of processing a belly for pre-cooked bacon includes injecting a belly with 1 to 3% by green weight of the belly of a solution comprising water, sodium nitrite, and sodium erythorbate to create an injected belly. The injected belly is tumbled under vacuum with dry ingredients comprising salt, sugar, and dextrose to create a tumbled belly. The tumbled belly is molded in a mold and then frozen in the mold to create a hardened belly. The hardened belly is removed from the mold to create a molded belly. The molded belly is sliced to create belly slices, and the belly slices are cooked.
