That said, a party this size needs about 4 people in the kitchen and 9-10 people out front to set up, serve, and cleanup the wedding. All of these will be working during the service- not at the wedding. Local church kitchens and diners that close after lunch are an few possible sources.

Now on to the menu for 150 (this count includes all the family and guests).

Pulled Pork- about 40 pounds raw pork, I like shoulder rather than loin, as it is juicier.
about 6 quarts table sauce, assuming it has some on it already.
Smoked peppery turkey breast- 20 pounds
Ham- 10 pounds
Assumes all are sliced for sandwiches. Consider adding 6-8 pounds of sliced cheese. Sandwich trimmings, lettuce, tomato, etc, on the sandwich planning page, tomatoes, mayo, mustard, etc. Do for 100.

Scalloped potatoes, 45 pounds potatoes
Spanish rice, 6 pounds rice

Green bean casserole/with mushroom soup- see the ellen's better green bean casserole on the Big Pots page; 2 1/2 recipes
Canned corn, 5 #10 cans

Fresh Spinach Strawberry Pecan Salad with honey and strawberry dressing.
12 pounds spinach, 8 quarts strawberries, 3 pounds chopped pecans (about 2 quarts). 6 quarts dressing

Coleslaw, 4 gallons

Dinner rolls-5 for every 4, plus 4 pounds butter
Buns for pulled pork- suggest slider size- 200

Beverages:
Ice tea, do 1/3 unsweetened, 12 gallons
coffee, use number of estimated coffee drinkers, and do dinner level coffee, beverage planning page
soda, figure approximate number of mpeople and use the proportions on the beverage planning page to figure how much of what kinds.
beer- keg serves 40 serious beer drinkers (4 servings per beer drinker)
wine, see beverage planning page, has for toasts, and for dinner needs.
Water- 2 bottled water if it is outside or lengthy

Snack mix for before the bridal party arrives. Please consider expanding, and here is why:

Before the Buffet; Why You May Need an Appetizer Table
A self-catered buffet is a real challenge to the organizers, and things don't always come together as smoothly as hoped. By planning and setting up an appetizer area or "nibble table" which is ready when the guests begin to arrive, the cooks and servers have time to complete the arrangement of the dinner buffet. This is especially critical if there are children among the guests, or there is a wait before dinner, as at a wedding reception.

This does not have to be complicated. Three items, plus a punch (6-8 gallons per 100), or two if one is alcoholic, are sufficient. Typically, include a fruit tray, a cheese tray and an attractive dip or spread; or you can go with a dinner theme such as TexMex with chips, salsas, Texas caviar and guacamole; Italian with bruschetta or antipasto; maybe shrimps or other cold seafood, if budget permits.

One appetizer service area is suggested for each 100 guests.
