Salmon bites (I use the wonky packets that aren’t evenly sized if you know what I mean and cut into bit sized bits for them). Plain for the kids, some sort of spice or rub for adults with rice or grains (often a cheat microwave pack) or new potatoes and a veg or two (something green usually but tomato’s/peppers/courgette roasted together also works).
’mexican’ - rice, homemade refried beans, cheese, salsa plus hot sauce or jalapeños for the adults. Depending what I have in it’s served as a bowl meal, a burrito (kids get it deconstructed style), tacos or quesadillas. I stick pepper sticks, baby sweetcorn and baby tomatoes on the side to up the veg quota. Homemade beans because apparently the pre-made tins have a texture one of mine won’t touch. You could add avocado or guacamole but none of us like it.
Omelette. Great way to use up all the random bits of veg in the fridge.
Traybakes as someone already mentioned.
roast dinners are a winner so if I do them I do enough to get a mid week roast out of the leftovers.
Barbecue. Chicken or pork steaks and a couple of salads. Eaten outside. Picnic is also popular with mine. Doesn’t really matter what it is. The importance is in eating it on a picnic blanket on the grass.
pesto pasta. Mac n cheese. We’ve recently convinced ours to try lasagnas. Spinach and ricotta lasagna is particularly fast to pull together.
Homemade kabab. Pitta (the one year old gets strips of pitta with the stuff next to it instead of stuffed into it). Lamb koftas or chicken skewers or falafels. Salady stuff - lettuce, white or red cabbage, etc. Quick pickled red onions. Hummus/garlic sauce/chilli sauce/whatever you like really.
