By Christina Morales, The New York Times During Passover, Jews move culinary mountains with matzo: cheesy lasagna with layers of the unleavened bread instead of noodles; peanut and caramel brittle; homemade pasta; and even pizza. It’s one of 10-year-old Hudson Greenstein’s favorite foods. During Passover two years ago, he was craving pizza when he and his father stopped by one of his favorite neighborhood restaurants, Nick’s Pizza & Ice Cream in Armonk, New York, to pick up a salad for his mother. That’s where he got the idea to sell matzo pizza.
