This trip, Guy Fieri’s firing up meaty meals and veggie specialties. In Modesto, Calif., a funky spot servin’ up Portuguese sausage and a lights-out lamb burger. In Oakland, a vegan joint with outrageous okra gumbo and a meatless spin on succulent sandwiches. And in Islamorada, Fla., a carnivore’s paradise dishin’ out wicked wings and righteous pork rinds.
