To keep our grocery budget in check, I plan weekly dinner menus. This school year, I've also planned a loose lunch menu. We fill it in each morning with what sounds appealing, with a refillable bottle of water.
Mo: Homemade "lunchables" (crackers, toppings, fruit, etc.) -- Yesterday was sliced cheese, turkey, Triscuits, carrots, for one child; feta cheese crumbles, Triscuits, sliced apples, and plain yogurt for the other.
Tu: Breakfast for Lunch (cereal and milk, oatmeal and fruit, yogurt and fruit, hardboiled eggs) -- today was 1) plain yogurt with a teaspoon of strawberry preserves and Grape Nuts to put on top, Wasa crackers, and sliced apples coated with lemon juice; and 2) a bagel with cream cheese, and grapes.
We: Sandwich and fruit/veg
Th: Dippables (apples, pears, crackers, carrots, celery; PB, cream cheese, hummus, etc.) with a side of protein or veg, depending on what's missing.
Fr: If they've succeeded in bringing and eating the week's lunches without complaint, they can buy the basic school lunch.
