What is something really yummy that I can have for dinner tonight?

I am going on a very strict & limited diet starting tommorow, doctor prescribed & he told me it should take a good 4 months for me to get to where I want & should be in weight. I can't have anything like chips, pizza, soda..etc.. SO WHAT CAN I HAVE FOR DINNER TONIGHT??? Sort of like a farewell dinner...I love pizza so I was thinking that...any suggestions???
