I found, when dd was small especially, that coming in and starting food was a killer.
But if I came in and had to reheat a sauce, boil a kettle and cook pasta/rice, and could turn around to emptying bags, hearing the days' news, dealing with homework reading etc before dinner - it was much easier.
So I would make a double batch of a sauce on a Sunday while cooking a roast dinner so in the kitchen anyway - spaghetti Bol sauce. A curry, chilli con carne etc. Or make a couple of full pies - shepherd's, smoked fish and broccoli (potato topped), chicken and mushroom (shop bought pastry topped), lasagna etc.
One half of the batch was for Monday's dinner (reheat sauce on arrival or set the pie in the oven on timer to be done shortly after we were due home). And the second half was frozen. Later in the week, I would take out a frozen dinner from a previous week for the same kind of easy prep.
The other cheat was to prep dinner the night before. So after having eaten dinner, when doing the cleaning up and washing up, I would peel and chop veg and potatoes, chop and marinate meat, ..pull a bag of marinated meat from freezer ... basically all the grunt work for tomorrow so all I needed to do was turn on pans and cook so even a stir fry was an easy dinner as it was open tuna and put into the pan in the right order. Or prep a traybake, that I could set on a timer in the morning or just throw in the oven when I got home at night.
Sometimes I would buy the veg already prepped but I didn't like to cost and the amount that got wasted in our house. But doing it after dinner when the chaos of arrival home was gone and people were fed and settling into the evening, worked better.
When I did my food shopping, I would chop my meat up and freeze it in dinner sized portions, and sometimes season it before freezing as well. And I also kept things like oven chips (potato and sweet potato varieties) frozen veg and some easy dinners in the freezer for nights when things went awry.
Sorry, I know that's what you weren't looking for - but it is what worked well for DH and I both working very FT hours and having a small dd to feed, and later when he had to do 4 years overseas and I had to manage young primary school dd on my own in the last recession (while still working more than FT hours).
