It's a snack

It's amazing how much a teenage boy can eat when he walks in from school.
Today it was a huge piece of lasagna, a few pieces of leftover (homemade) pizza, a yogurt and a huge glass of milk.
"Don't worry, I'll still eat dinner."
Not sure if I'm worried about him eating dinner.  Just worried if we are going to have enough food at dinner for the whole family, and for the rest of the week.
I better go plan another trip to Costco.
