It's all about planning and organizing your meals. I think about what I want to make for us each week and think about how long each dish takes to cook, how long it takes to prep. Now we have plenty of time to cook so it doesn't stress me out as much as it used to a few years ago but it can be done.
The above containers with soup for instance took 45 minutes to make, from preparation time to finish. I used an Instant Pot, electric pressure cooker, but you could do the same in a slow cooker and just cut up all your veggies and set it on slow for 8 hours before you start driving and it'll be done when you're ready to take your mandatory break so you can divide it into bowls and let it cook off, or eat one, whatever you plan.
If you were to cook this from scratch in the Instant Pot like I did, you could do this during your 30 minute break, take 15 minutes extra and have 2-4 meals which saves you time down the road.
2 chicken breast filets
carton of organic vegetable broth
half bag precut carrots
4-5 chalks celery cut
5 cloves garlic minced
2 bay leaves
a pinch of thyme
14.5 oz can of organic fire roasted tomatoes
2 pepperoncini peppers diced
Put everything in the pot, set on high pressure for 20 minutes and shred the meat with 2 forks when done. I filled my IP for 3/4 full and did a quick pressure release. If you fill the IP to the max this isn't recommended. Please be careful to not burn yourself! Enjoy!
