What do you enjoy eating?
Is it possible it tastes bland because you’re used to so much salt in ready meals etc?
Try one meal a week, on a day you have a bit more time. And make it easy at first too.
Can you buy a jar of sauce, and some ready made, but fresh meatballs.
Cook it and some pasta (pan of hot water, set a timer, and just leave it - timer is key!)
And that’s a cooked meal, that’s better than a ready meal, but not too much for you to risk getting wrong if you struggle cooking.
You could try it the next time and add some chopped veg or even frozen veg into the sauce.
Other quick and easy things that are a bit healthier could be some soups and things like that, that you can buy ready made.
I’m also a fan of a pasta bake, you can literally buy a sauce, some veg, add some water and dry pasta and put it in the oven, covered in foil for a bit,
Then take the foil off, add some grated cheese and let it go nice and brown on top.
You can do home made pizzas.
Cous cous is basically impossible to get wrong and there are a million things you can do with that once you figure it out
If you can do eggs and soldiers that’s great nutritionally but super quick and easy and cheap too.
Don’t be ashamed anyway, it’s hard having time and money to feed everyone, trying something hard and then having the kids hate it!
Don’t do too much at once. Make one meal a week slightly more ‘from scratch’ or with a bit more veg in. Then next week see if there’s another little real you could make. And so on, it could be as simple as adding some veg on the side of their nuggets and chips. Or getting the kids to try one new fruit or veg
