For crazy weeknights, dinner in a bag that isn't takeout

Life is busy. We don't always have the luxury of thumbing through our favorite cookbooks, marking appealing recipes with sticky notes for dinners sometime off in the future when we will somehow have time to salt-cure a cod or dry-age a side of beef in our garage fridge. Sometimes, we just need to get dinner on the table. It doesn't have to be fancy, but it should still be tasty and nutritious.
