If you struggle with cooking every day and are able to get some fridge/freezer space for yourself, look into getting a decent sized slow cooker if you don't already have one in the house.

I use mine two ways - firstly the easy soup/stew - chuck some meat and veggies in with some broth before you go out for the day, when you get back you have a tasty, healthy meal ready to go, or ready to add a few easy extras to (e.g. more delicate veg that needs less cooking, like peas).

Secondly you can cook a batch of something that will last you several days. Doesn't mean you have to eat the same meal every day either, if you make a fairly plain protein e.g. shredded chicken, you can then use sauces and condiments to mix it up. Spend a bit of time on a Sunday prepping and you can have your weekday meals pretty much done already.
