Good luck with the job, I am willing to bet you will find going back into the work force has a whole lot of plusses. I went back to work two years ago and I love it.
I would suggest making a list of meals your family enjoys. Then think of which one's can be made quickly, which one's could be made ahead, and which one's could be made while you go to work (such as the crockpot). Since part of your motivation to go back to work is to pay off some debt try to stay away from the convience foods. I see so many recipes for quick meals that call for ingredients that add up to so much it would be cheaper to eat out each day. Think budget.
Some meals my family likes are:
Salads with tons of toppings
spaghetti and sauce (we serve it seperate so kids can choose if they want sauce or not). -----The slowcooker makes great sauce too!
Burritos where everyone gets to pick their fillings
Home made pizza (toss bread ingredients in the bread machine and set for Dough) it will be done pretty quickly and you can add your own toppings.
We love pizza's made with pita bread too. A local grocery store sells large pitas which work great.
Soups can go together quickly. Chicken, Beef vegetable, lentil, and Corn Chowder are all tasty.
---one soup I like is really made from a bunch of cans (broth, garbanzos, tomatos I forget the rest but you get the idea).
Good luck! and Enjoy working, it will be great to get your own paycheck again.
