Lasagne or pasta bake, if you have a couple of trays big enough. Or slow cooked lemon chicken with roasted new potatoes and salad.
I rarely make lasagne any more, instead I make a pasta al forno with meat sauce. Basically you make the meat sauce and the white sauce, cook some big pasta shapes and then mix the three together, put it in a big ovenproof dish, cover with some cheese and bake for 20 minutes.
Lamb Tagine in large slow cooker(or two) which can be taken to table in the slow cooker pots, chicken and lemon kebabs, roast veg couscous, pitta breads, salad (when I have children coming salad includes a plate carrot, red pepper and cucumber sticks, cherry toms and apple slices here)
Do enough so everyone can have both the meat dishes (they won't but good to be able to offer the choice to everyone) then your dinners for the rest of the week are sorted from the left overs
