@rbreich like most of you, I bring a lunch to save money and time and for healthier options. It cuts down on plastic, since I use the same pyrex, thermos, bag, and silverware. I mean, who wants to eat off plastic?
Since I teach high school, I feel like I'm setting a good example. Have you seen teenagers eat? Beyond the cafeteria staples of pizza and fried food, it's a steady diet of monosodium glutamate and high fructose corn syrup. The best part is the conversations about food and life.
