Dane, this is a complex menu. Is it a family party or a paid event? The menu needs some work, and the type of party affects flexibility.
I have made some basic estimates, but would not guarantee my usual close results.
corn muffins (mini)12 dozen
Cinnamon rolls, get small ones, about 100
3 pounds butter, add honey and jam
Egg /ham Breakfast casserole, 9x13"
Blueberry French toast casserole w/ syrup, 9x13"
9-10 9x13 of each
Chili & Oyster crackers- serve for 60, 4 pounds oyster crackers or saltines would be very traditional, 2 pounds grated cheese
Link Sausage- see breakfast planning page
Spinach salad w/dried cranberries & walnuts
12 pounds fresh spinach, 2-3 quarts each cranberries and walnut pieces
Fresh veggie tray- I would skip, or serve broiled tomato halves, 1/2 per adult person
Fruit tray with fresh Pineapple
strawberries & choc. fountain
For these two items, see the chocolate fountain article and the fruit tray page
Yogurt w/ berries & Granola, I would put all the fruits on the fruit tray. 3 gallons yogurt, and consider doing vanilla or honey, not plain. 6-8 pounds assorted granola, have at leas one gluten free and labeled.
cider & grape juice- mixed? would do cider and a citrus, rather than grape, use beverage planning page and do each for 100, some left
coffee- use beverage planning page
