Figuring serving size
 

My mom brought me this for lunch today http://recipes.sparkpeople.com/recip...?recipe=403227

It makes 12 servings. I ate 1 cup. How can I figure my calories for the 1 cup?

She didn't bring all of it so I couldn't try and base it off the amount after it was made. Just needing some suggestions.

My guess, and it's just a guess, would be that a serving of this recipe is probably about a 1/2C. Hopefully someone has made this before and can tell you.
