A slow cooker is a lifesaver for me. I’ll put a big roast in on Sunday get 2 dinners for my family of 4 and an easy cold lunch for me out of it. My friend gets 3 slow cookers going on the weekends for the week’s meals - she has 4 kids and 2 parttime jobs.
An Instant Pot might be the way to go now!
Anything that can be pre-made when you don’t have a 14 hour workday is helpful. Even forming burgers, making a meatloaf, things like that. For me, the biggest Way Of Eating derailer is allowing non-confirming food into the house or giving in to temptation outside the house. Then I have to take some deep breaths and decide which means more to me: indulging for that taste or declining for my health.
Scrambled eggs are probably my favorite go to when I have no time to make a real dinner - and the Eggs Are Only For Breakfast Police have yet to stop me!

I raise grass fed beef!

I work full time and barely have time to breath during the week after getting home, going to the gym, walking the dog, showering and catching up on whatever needs to be caught up on .

I have found that if I prep all my food on the weekend I do better during the week. I use my instant pot. I usually make a whole chicken that can be shredded or used for tons of recipes. I use the bones for bone broth, so I always have that on hand. Sometimes I make a corned beef or roast beef, and then I have it ready for the week.

I also make tons of hard boiled eggs and can eat those for snacks/breakfast, and I prep all my vegetables (cucumbers, carrots, etc.).

Planning and prepping are the most important to me I think.

I use my instant pot for everything (I am definitely a convert). During the week, if I haven't prepped anything, I can make curries in 10 minutes or can make chicken soup while I am at the gym.
