Just in case you ever need to cook a real meal for a crowd, here's a plan and shopping list that feeds thirty people for $60, and won't kill you to get it done.
Meat loaf:
5 lbs. ground chuck
2 lbs. ground turkey
2 packages frozen mirepoix mix (chopped onions, celery, carrots--sautee ahead of time)
bottle of ketchup
bottle of Worcestershire sauce
small box of oatmeal
Mashed potatoes:
lots of potatoes
bottle of half-and-half
pound of butter (don't use it all)
Big pot of mixed greens:
bag of kale
bag of collards
bag of turnip greens
Bowl of fruity jello:
8 small or 4 large boxes of raspberry jello
large can of sliced peaches in light syrup
3 cans pineapple tidbits in juice
This will not be the most elegant meal ever presented, but it will feed people comfortably for about two dollars a person.
Order of works:
Make the jello early in the day and leave in the fridge to set. Start the greens before lunch with some broth, bacon grease, and red pepper flakes. Mix the meat loaf around 3:30 and shape into four large loaves in a big roasting pan and stick in the oven. Last, peel those potatoes, cook and then mash. Dinner can be served at 6:00 and the clean up is not too bad.
You may never have to feed large groups of people. I, on the other hand, seem to have one of those chalk marks on me like tramps used to put on houses. But I don't mind!
