I like to go totally 70s and have new potatoes with quiche (homemade - cheese and onion) with a salad made of lettuce, cucumber, spring onions and radish, plus salad cream.
Also:
stuffed peppers and salad plus tsatziki
M&S veggie kievs and salad or vege
Sainsbo's frozen nut cutlets and salad or vege
mushrooms stuffed with walnuts and Stilton and baked
