Your overall numbers don't look too bad, especially for such a carb heavy meal, but it's still a pretty hefty spike. My concern would be that maybe right now your diabetes isn't very advanced, and you can handle this very carby meal (more or less), but if you keep on doing it, your insulin resistance might get worse. Personally, I think if you need it as a once a month pick-me-up, you can probably get away with it, but from an actual health point of view, I'm not sure it's optimal.
Whether or not you are on medication could also be a factor to consider. My dad (diabetic, elderly) eats pizza and potato every day, albeit in small portions, and he's doing fine- in his case he's very physically active, and he takes a lot of metformin and gliclazide. It's not my way, but it evidently works for him.
