All the ideas sound great,
I would make a few baked chickens,
they are cheap and versatile,
and some veggies.
and seasoned baked potatoe pieces on a tray
with the baked chicken you can serve them as the meal,
or break off the left overs into the salad, or the veggies.
kids always like potatoe, and they reheat well.
can be reused as a breakfast treat, or mixed with the veggies or chicken.
veggies are healthy a super easy.
and can be reheated.
and the salad is another healthy option with can be eaten for lunch, with the left over chicken.
