During the weekend, I make meals that I freeze in batches - lasagne, bolognese, pizza swirls, soups, pies, burger buns, other baking and so on. It's easy to thaw and reheat on those days where there's no time and/or energy to cook.
Salads are nice and quick too. I like Mexican style salads, sometimes served with refried beans (they take 5 mins to make).
Fried pork chops or ovened chicken, served with pasta with mascarpone and chopped parsley, and ovened courgettes with garlic (and maybe mozzarella) on the side.
Burgers - it's just to shape and fry the mince (I only add salt and pepper to the beef mince), chop lettuce, tomatoes, cucumber and so on, and toast buns.
Open sandwiches - as a kid, my mum would just arrange the cheeses/meats/vegetables and so on in bowls and on plates, and despite it being very simple, it was lovely.
Thai curries are nice too.
Spinach and lentil curry - I use red lentils, and sometimes add chicken.
Lentil dishes.
Couscous dishes - oven chicken legs/breasts, make a salad (I like simple tomato-based salads for this), and make a mint/lime/garlic/olive oil dressing for the couscous.
