I am the one on the "make it from scratch" bandwagon, but the ex and DD will settle for hamburger helper (ugggg! I eat a sandwich that night LOL)
I started this back when DD was teething at 8 months and he and I were working 50+ hours per week. The only way I was able to actually get it worked into my schedule was to plan the meals by the week, then double up on the meat or veggies or starches ... for example, if we were going to have stir fry on monday and then bier ox on wednesday, I would cook a double batch of rice and refrigerate half for the next meal. Yes, I use rice in my bier ox instead of cabbage/sourkraut
Then, if we were having spaghetti on friday, I would fry a double batch of hamburger, one for bier ox and one for spaghetti, seperate it before adding the spices and refrigerate half.
I would also do most of my cooking on either saturday or sunday ... saturday at that time was also laundry day at the laundromat and grocery shopping for the next week.
I would also cook the fresh vegetables that were going to have a short shelf-life or blanch and freeze in meal-size portions.
Now, I generally can or freeze enough garden vegetables each summer to get us through to the next harvest.
As for meats, I am lucky to have a custom butcher shop in town that sells off any "extra" and can get grass-fed, grained beef, chicken and pork. Like the butcher says, if folks are raising for themselves, they DO NOT put chemicals in those animals
There are times when this process will "break down" and I have to buy from the grocery stores, and I can definitely tell a difference in how my body reacts ... most prepared items such as the hamburger helper have so much salt and/or MSG in it that it gives me a terrible headache the next day.
One thing we do have to watch out for in my area is beef that has been pastured where there is too much sage brush as that will definitely leave a "twang" to the meat! LOL If only someone would develop a miniture cow that I could have on my city lot here in town LOL
