Fast food nutrition-without bread/buns/etc.

I'm on a ketogenic diet (standard keto 20g or less of carbs daily) I have kids. Occasionally I need a fast food trip between after school robotics, chess club, ballet, guitar, and dance class some days I'm not looking dinner. You can still eat keto you just have to be smart. Example I want to eat am egg McMuffin, no muffin just egg sausage and cheese, or an open taco from Taco Bell, or open roast beef from Arby's etc, I'm not seeing a way to document that food without those added bun/bread/tortilla carbs.

Is this possible and I'm missing it?
