Wrong time to start again

It's kinda the wrong time of year to try to start this again, but I really need to get back on the Primal wagon. Me and hubby went primal about 8 months ago, for 2 months, and we both loved it, lost weight and felt terrific. Then I had to get a part time job (on top of my full time job) and I just don't have the time I used to have to dedicate to food prep. I need ideas and (encouragement!) to get this going again. I need as many crock pot ideas as possible because three days a week I get home after 11:00pm (and I work weekends) and if I hadn't already made something, we usually end up at the only place that's still open - Whataburger or Taco Bueno. So obviously in the past 5 months since I got my PT job, I've gained all the weight back, gotten the normal cold/flu and pneumonia, and we just feel like crap. My energy level is so low all I want to do is sleep between jobs and I end up drinking alot of coffee just to keep going.
Here's an idea of our typical day:
Hubby is a plumber, so I need ideas for his lunch w/out access to microwave
I work in an office 8 hrs, get off at 4:00 and go to part time job at 7:00. Work from 7-11 come home and try to sleep after drinking coffee earlier to keep up with 2nd job.
When I put it like that...it seems like there should be time for everything, but during the times I'm not working I just want to sleep.
Help if you have any ideas, please. I know this is the plan we need because it works. I just feel so lost trying to get back in it.

Now and then it is good to pause in our pursuit of happiness and just be happy.
