I didn't have a favorite lunch really. I liked turkey and mayo sandwiches cut into quarters when I was younger, then I guess PB&J. I usually had a chip or cracker, and some type of fruit product, whether it be the real thing or a fruit "snack". I didn't usually get desserts. I had juice boxes to drink but sometimes I got milk. My school's hot lunches were alright, I usually got the chicken nuggets each week, sometimes the pizza. I also liked their nachos and french toast sticks. For a couple years they had awesome pre-made salads too.
A friend of mine, no joke, had nothing but fruit snacks in her lunch from at least 4th grade to 6th grade. Her mom would pack it for so, so it'd be like fruit by the foot, a fruit roll-up, and a String Thing. Maybe some sort of "dessert" type food too. And she would drink milk, I guess her mom thought that was where she would get her nutrition.
