My suggestion- an 8 week rolling meal plan.
ok, it does take a lot to prepare it, but once done you can keep it going for years. With maybe just an occasional swop out. I found 8 weeks was long enough for family to say “we haven’t had that in a while”. A few favs I put on once a month,
I also went one step further in having a spreadsheet with the shopping list for each week on meal plan.
that then completely eliminated thinking and made shopping quicker- I also shopped on line when was working full time so I could save those shopping lists and make even quicker.
In terms of cooking- you HAVE to get someone else to cook occasionally. If you do all cooking,why? Your partner needs to step up at least once a week to cook. Then have one ready meal/ takeaway each week . That then gets you down to 5 meals to cook. You might also think about 1 meal a week that, while fresh, is a bit of an assembly job or very quick…spag carbonara, tray bakes etc are really minimal effort, or I go for a piece of grilled fish, new potatoes boiled in jackets (no pealing) and some broccoli and frozen peas. No prep really, a couple of pans and you’re done very quickly.
in terms of getting others to cook, start your kids young. Mine were “helping me” from age 4 with stuff like prepping veg - even a small child can break up mushrooms with their hands into small pieces. A small child can wash veg etc. then progress them, get them interested and skill them up form early age. I would do things like get the, to help me add herbs and spices and get them to smell things, taste stuff while cooking. Never had fussy eaters as they had vested interest at early age. By 13/14 my two were taking it in turns to cook a meal each week from the menu ..so once per fortnight each. By 17/18 I was not “allowed” to cook certain things as their version was better than mine 🤣🤣🤣🤷🏼♀️ Who was I to argue? . But in fairness they had a good role model as my ex also cooked well and we split cooking 50:50
