I'm surprised that no one has mentioned Mrs Beeton - given that seems to be what leshy is after ...

http://www.mrsbeeton.com/40-chapter40.html is a list of her proposed menus but the whole book is there.

I particularly like her picnic:

BILL OF FARE FOR A PICNIC FOR 40 PERSONS.
2149. A joint of cold roast beef, a joint of cold boiled beef, 2 ribs of lamb, 2 shoulders of lamb, 4 roast fowls, 2 roast ducks, 1 ham, 1 tongue, 2 veal-and-ham pies, 2 pigeon pies, 6 medium-sized lobsters, 1 piece of collared calf’s head, 18 lettuces, 6 baskets of salad, 6 cucumbers.

2150. Stewed fruit well sweetened, and put into glass bottles well corked; 3 or 4 dozen plain pastry biscuits to eat with the stewed fruit, 2 dozen fruit turnovers, 4 dozen cheesecakes, 2 cold cabinet puddings in moulds, 2 blancmanges in moulds, a few jam puffs, 1 large cold plum-pudding (this must be good), a few baskets of fresh fruit, 3 dozen plain biscuits, a piece of cheese, 6 lbs. of butter (this, of course, includes the butter for tea), 4 quartern loaves of household broad, 3 dozen rolls, 6 loaves of tin bread (for tea), 2 plain plum cakes, 2 pound cakes, 2 sponge cakes, a tin of mixed biscuits, 1/2 lb, of tea. Coffee is not suitable for a picnic, being difficult to make.

Things not to be forgotten at a Picnic.

2151. A stick of horseradish, a bottle of mint-sauce well corked, a bottle of salad dressing, a bottle of vinegar, made mustard, pepper, salt, good oil, and pounded sugar. If it can be managed, take a little ice. It is scarcely necessary to say that plates, tumblers, wine-glasses, knives, forks, and spoons, must not be forgotten; as also teacups and saucers, 3 or 4 teapots, some lump sugar, and milk, if this last-named article cannot be obtained in the neighbourhood. Take 3 corkscrews.

2152. Beverages.—3 dozen quart bottles of ale, packed in hampers; ginger-beer, soda-water, and lemonade, of each 2 dozen bottles; 6 bottles of sherry, 6 bottles of claret, champagne à discrétion, and any other light wine that may be preferred, and 2 bottles of brandy. Water can usually be obtained so it is useless to take it.
