Pre-Wedding Appetizers (120 people)
Ham and Apple wraps topped with yogurt dijon sauce Apples are quartered with 1inch piece of ham wrapped around it.
I would do apple slices, not quarters, be sure they are dipped in citrus or Fruit Fresh to prevent browning, and have both a deviled ham dip and a caramel dip- 1 cup each per 8 guests
Apricot-Basil chicken salad on crackers- skip. Messy to eat, and not the right choice with sandwiches as the main course
Caprese Salad Skewers - one mozz ball, one cherry tomato, one basil leaf
I would do these as platters, with cherry tomatoes as the outside ring, mixed gardiniera and olives as the middle ring and the caprese balls as the inner ring, tons to serve. 1 pound tomatoes per 10-12, 2 gallons gardeniera per 100, 2 balls per person
Fruit Trays- use the fruit tray page. 1 1/2 the deluxe tray for 100 would be plenty

Main Course (170) people)

Sandwiches
Turkey, Ham, and Provolone in a Croissant
w/Tomato, Lettuce, purple onion, lite mayo
and mustard
Skip the onion, or have it on the side. Put mustard on the table; many people don't like it. Have mini croissants and do 1.2 turkey per person plus 1 ham per 2

You also need 20-30 egg salad or another vegetarian option.

Spinach Salad with sliced Strawberries, sliced
almonds, and Feta with poppy seed dressing
per 100, 10 pounds spinach, 2 pounds almonds, 6 quarts strawberries, 3-4 quarts dressing. Put the feta on the side, crumbles about 3 quarts per 100

Potato Salad red potatoes with skin on, chopped
green onion, chopped bacon, sliced black

Add an interesting bean dish such as 3 bean salad or Texas caviar, OR corn-black bean salsa, something colorful and a bit different.2 gallons per 100.

olives, 3-4 quarts per 100
dill pickles, 3 quarts per 100, 1 quart cornichons or bread and butter
