A lot of ours is stew/bologneise/similar based as we use the slow cooker, and take the leftovers to work the following day. OH will cook a roast one week day as he has a week day off as he works a day at the weekend. His daughter doesn’t like spicy so when she is there it’s pasta bakes, lasagne, cottage pie etc. Towards the end of the week I tend to make a curry or ‘stroganoff’ out of whatever is left in the bottom of the fridge!
One of our favourites is making pizzas with portobello mushroom bases - it’s in the Michael Mosley book but is simple to adapt. We have them with salad or BNS wedges.
Fajitas, curries, stir fries. A real comfort food for us is something like poached haddock, crusty white bread and poached egg.
Things that can be done in one tin - chicken thighs or salmon with roasted veg and then cous cous.
Jacket potatoes are under rated I think - done properly in the oven.
Lamb steaks grilled and served with cous cous with apricots, peppers, feta, chilli and apricots run through.
Quite often buy the M&S dine in deal when it’s on and have it on a week day or freeze it for another day.
I got a recipe years ago from the Waitrose website (I think) for sweet potato and chorizo chilli which is really nice on its own.
A simple dahl is really flexible - I often have it if I’m in on my own with some mushrooms and tomatoes and a naan.
It’s easier in the summer because you can just do some form of protein and a salad. In the winter you feel like you want a bit more.
I do WW and it has a good thing in the app where you can put in what you have and it suggests things to cook.
