Well I don't know that we're perfect either but some ideas for you, nothing very exciting or revolutionary but reasonably low effort. You can also ask chat gpt giving it constraints around what you like and how much calories/protein/fibre you want in each meal and how much prep time and it's pretty good at making you a meal plan accordingly.
Breakfasts
Overnight oats
Eggs on toast
Beans on toast
Greek yoghurt with berries or banana
Pancakes
Lunches
Homemade soup
Salad (proverbial MN massive salad with your choice of cheese/nuts/meat/tuna as a protein, some grains as carb and lots of different vegs not just boring salad leaves e.g. roasted peppers and courgettes, olives, gherkins)
Dinner leftovers
Sandwich with cheese/tuna (avoid heavily processed meats)
Omelette
Any item from breakfast menu
Dinners (we're veggie so make veggie versions of these using beans/pulses/lentils or tofu or nut roast in place of the meat)
Stir fry or rice bowls
Chilli
Pasta with homemade sauce e.g. bolognese
Roast dinner / meat n 2 veg
Shepherds/cottage pie
Burgers

Fajitas/burritos
Tray bake or one pot dish from a tray-based/one pot recipe book e.g. the green roasting tin.
Greek yogurt and fruit, or cheese and crackers or nuts/seeds/dried fruit mix, dark chocolate for snacks/afters.
I find not drinking or reducing alcohol intake plus minimizing the amount of processed and junk food in the house a huge help as (a) having even a very small amount of alcohol enormously reduces my inclination to make good choices and (b) if it's there I'll tend to eat it regardless of if I'm actually hungry/ enjoying it or not. I do still indulge from time to time but try and keep it to outside the house as much as possible.
The things that take longer to cook from the dinners list I will save time by batch cooking several portions in one go and freezing, usually at the weekend so mid week dinners can just be reheating the main element and preparing some carb/veg to go alongside.
Good luck!
