It is virtually impossible to estimate the carbs in a meal like that correctly because most of the elements are very high carb, so guessing wrong about how much noodle you ate by only 1/2 an ounce in the noodles might be a difference of 18 grams, guessing wrong about how much cornstarch is in the sauce might make a difference of another 10 grams, guessing wrong about how much starch is in the eggroll wrapper might add another 20 grams so your educated guess can, worst case, be plus or minus 50 grams!
Try buying some chinese noodles and weighing them on a food scale, and then cooking them up. I’ve done this with pasta and it was a great way to realize that a very tiny portion of pasta is about 56 grams! The portion you get in a restaurant is usually 4 times that or even more. So 1/2 of that is still twice what you think you are eating.
A relatively small portion of Vegetarian Pad Thai contains about 103 grams of carbs but again, you’d have to weigh your portion and remember that the noodles might have taken up a different amount of liquid than the ones tested in the lab. Which is why I don’t eat noodle dishes. I love pad thai, but I have never yet been able to eat a portion and get a blood sugar under 200 mg/dl! With insulin! (My usual target is to be under 140!)
When I was controlling by diet alone I used to get the spareribs (minus sugary sauce) or the duck, or teriyaki beef sticks no noodles, no rice, and hot and sour soup. There is sugar in all the meat–I used to call Chinese American food “Meat sundaes” but less than in the thick sauces and of course the rice, egg rolls and noodles.
