I genuinely checked to make sure this post wasn't by me having some sort of a breakdown as I made pasta with jarred pesto and peas and sweetcorn for me and DH today, having no time to cook because of my older child with ASD (and a limited diet!) and a new baby...
Anyway my other fave meals are:
Cheese and mushroom omelette, served with cucumber and cherry tomatoes
A big pack of stir fry with a can of chick peas stirred in, served with packet rice and an optional fried egg
Fried halloumi (takes five mins) with boiled broccoli and cauliflower
Beans and cheese on toast with a couple of portions of fruit for afters
Tinned mackerel served with some quick veg
Tuna mayo wrap or jacket potato and quick veg
Pitta bread pizza and quick veg
Pizza wrap (get a wrap, top with tomato puree and grated cheese, top with another wrap and squash it down, bung in the microwave for about a minute).
My other top tip is batch cooking - I make some slightly more complicated recipes (curry, chilli, Bolognese, arrabbiatta) at the weekend when DH is around, but huge batches of them, stick them in the freezer and eat one portion a week.
And I also use a rotating meal plan so I never have to think what's for dinner, it's always one of these options which takes the mental load out of it for me in terms of planning and shopping as I always buy the same shop! Not very exciting but routine helps me keep on top of the chaos.
Good luck, and sending you lots of solidarity!!
