Here's what I do.

Starter - a)three different kinds of melon slices always good.
b)salad with slice of terrine and brown bread

Main - some form of stew/casserole. If lamb stew, serve with couscous and green veg. Carrots and parsnips in the gravy.
If beef stew, lots of mash and greens with the carrots as above.
Dessert - Fresh fruit salad with ice cream or sorbet or, if you have time the previous day, lemon posset (Gary Rhodes recipe) or syllabub.

Then fill up on cheese with bread and biscuits.

All easy peasy and not too expensive. Enjoy!
