When my son started KG, he refused to eat school lunches and wasn't a fan of sandwiches (that's now changed big time). What saved me was buying a thermos and making spaghettios every morning (or reheated leftover dinner). Middle school lunch lines were so hectic & long that he wound up packing sandwiches every day. Now he's addicted to the high school chicken sandwiches. I miss the spaghettios days.
