Flat and thin are “in” – regardless of whether you’re talking about televisions or cell phones. And now food follows design fashion. Kraft Foods, Northfield, Ill., is rolling out DiGiorno Crispy Flatbread frozen pizza, a four-item line with “premium toppings for grown-up palates,” the company says. Varieties include Tuscan Style Chicken, Pepperoni & Fire-Roasted Bell Peppers, Italian Sausage & Onions and Mushroom Medley. The line is available nationwide and items carry a suggested retail of $6.89.
