(“As pizza thrived in the US, Italian pizza-makers started copying the American approach * * * one of the more recent trends in Italy—topping pizzas with hot dogs and french fries as something of an attempt to out-American the Americans”)

(c) Neapolitan “Pizza association officials and owners of VPN-certified pizzerias say Neapolitan pizza is simplicity defined: The dough contains little more than flour, water, yeast and sea salt; the cheese is typically fresh mozzarella; and cooking time is a mere 60 to 90 seconds (those wood-fired ovens can easily reach 1,000 degrees). As simple as the recipe may be, learning the art of preparing the pizza is a whole other can of tomatoes, so to speak, boosters say (preferably, San Marzano tomatoes from Italy). * * * A Neapolitan pizza has a maximum diameter of 11 inches, as per the pizza association's rules. By contrast, a New York pizza often measures 18 inches.”
(i) San Marzano tomato

(section 3 Origins)
(ii) “a whole other can of tomatoes, so to speak”

This is grammatically correct way, which means “another whole can” (where “whole” is emphatic). The colloquial form is “a whole nother [noun, in singular form].”
(A) nother (adj; alteration (from misdivision of another) of other [as] adjective; First Known Use circa 1909):
"OTHER--used especially in the phrase a whole nother —used chiefly in speech or informal prose"

(B) whole nother thing:
“Rur. [short for ‘rural’] a completely different matter. (Often ‘corrected’ to a whole other thing. The word nother is a shortening of another.)

(“The dough must be kneaded by hand or with a low-speed mixer. After the rising process, the dough must be formed by hand without the help of a rolling pin or other machine, and may be no more than 3 millimeters (0.12 in) thick. The pizza must be baked for 60–90 seconds in a 485 °C (905 °F) stone oven with an oak-wood fire”)
(ii) Janet Napolitano served as Secretary of the Department of Homeland Security (2009-2013).

The southern Italian surname Napolitano denotes “someone from Naples, perhaps from Neapolitan dialect Napulitanë, an adjectival derivative of Napoli. Compare standard Italian Napoletano.”
Dictionary of American Family Names, by Oxford University Press.
(iii) In other words, “Neapolitan” is English, whose counterpart in Italian standard language is Napoletano.
