Two words:
Slow cooker (or crock pot, it's the same thing).
This is my saviour on busy nights. Perapre the food the night before and stick in the fridge. Then before I leave for work in the morning, I just take it out of the fridge, plug it in, set it on low and when you (or your husband) comes home there's a homecooked meal ready to go! Plus, it's the best thing to come home to a house that smells like food, it always makes me think "Is my mom here?"
