DH,DD and I are vegetarian, DS will eat chicken but not red meat.
DS will have a chicken breast (just roasted , plain)
I sancy doing something with filo pastry and spininach but I'll probably do that on the Saturday and we'll have a Quorn roast.
Roast potatos, steamed carrots, brocilli, peas, steamed white
cabbage Yorkshires,, gravy.
Easter I'd think lamb or chicken, (or both ) if you are feeding meat eaters.
No starters here (I don't do a starter for Christmas either)
Puddings -
something lemony , maybe a baked cheesecake .
an apple pie , must be nice crisp pastry and sharp apple ( Aldi do a really nice one , frozen)
something chocolatey 
, chocolate Brownies or those Gu melting middle puddings (really quick to cook )
I have asked everyone for suggestions here
We're doing veg grills /fish fingers(for DS) , chips , salad on the Friday
Quiche and coleslaw, maybe baked potatoes on Saturday
Sunday dinner as above
Pizza ( I put the dough on to mix in the morning then rise slowly to cook later) on the Monday
