Can you put how much of everything she's using in to the recipe calculator, and then calculate the number of servings?
Another option (which I do when someone else prepares my food and I can't measure on the front end), measure what goes on my plate (so an ACTUAL cup, not "about" a cup) and then try to guesstimate how much of that is Hunt's sauce, cheese, pasta, etc. Generally in that type of meal a serving will be mostly pasta, then meat, then cheese, with sauce being the least of what's on your plate. Of course each cook is different and only you know what's on your plate tonight.
Do something everyday that your future self will thank you for.
