Okonomiyaki, the Japanese style of pizza. I had some once at a place in Japantown; it's nothing like the Ranma 1/2 thing! It's like a big vegetable-and-meat-covered omelette, there's no dough or noodles at all! And it took half an hour to cook! Price wasn't bad though.
She deserves to marry Ranma more than Akane and the others, though. I mean, his dad ruined her life after promising him to her, she can cook way better than Akane, she's not an idiot like Shampoo, she's tough enough to raise a strong child for Ranma, and she's totally loyal to him, no big anger attacks like Akane.
