Baguette of French bread or Italian bread, Cuban bread, Jewish rye, or other favorite. Ready to eat meats include turkey roast, roast beef, corned beef, pastrami or any smoked products. In some stores you can find pre-cooked petite Cornish hens which would also go well with this picnic. Fruits I would include are apples, pears, strawberries, peaches and melons and grapes. Cheeses such a Camembert, Brie, Swiss, Canadian strong cheddar, goat cheese, or other ethnic favorites.
Wines can be varied.
I would bring one bottle of red Bordeaux or Beaujolais or white Chardonnay or white Briolo. As for Champagne, I like Rose D'Anjou de Neuville or Perrier Jouet, Corbel or Frixenet. An ice chest will keep your wine or Champagne cold. Don't forget the roses. All I can say is all you need is a little sunshine or the sound of the ocean waves and your sweetheart for a memorable romantic picnic.
