Hiram Monserrate is even worse at pizza than he was at politics, one thin-crust connoisseur told The Post.

The disgraced Queens state senator, booted from office after assaulting his girlfriend, is now abusing customers at his Papaya Pizza in Corona, Major League Eater Jason “Crazy Legs” Conti said after sampling a few slices.

“I would rather eat the cardboard box at Patsy’s before I’d eat this,” said Conti, who knows a thing or two about a good pie, having downed 21 slices in 10 minutes at last year’s Upper Crust Pizza Eating World Championship.

Serving up subpar pies will not help restore Monserrate’s image, Conti added.

“You can’t overcome bad pizza,” he said.
