Robert Irvine is sharing some of the most indulgent food that's stacked and stuffed with flavor. First, he's in New Orleans to try beignets stuffed with savory seafood or sweet berry cheesecake. In Denver, classic Venezuelan sandwiches are stacked with succulent simmered meat between fried plantain buns. Then, in Inglewood, Calif., Robert discovers red velvet strawberry cheesecake cake and a banana pudding cheesecake layered with homemade goodness.
