The clue for figuring meat for a crowd:  1/4 to 1/3 a pound per person.  However, the truth is meat does not come packaged that way.  So, guesstimate what is going to be most popular and go heavy on that product.  People will, of course, take a little of several things.  Trust me, no one will go away hungry!

4# pasta – mixed
3# angel hair pasta
marinara – 1#10 marinara + 1 qt
Alfredo  – ½ gal cream + 1 ½ # Parmesan cheese + ½  # butter (or check out               the *Fake Quattro Formaggi Sauce)
pesto  – 2 jars pesto
180 cooked shrimp – medium
10# chicken – cooked, sliced (or chicken tenders)
126 frozen meat balls – heated
5# Italian sausage – browned and drained
2# mushrooms sautéed
1 jar sun dried tomatoes
½ bag pine nuts
2# parm cheese
1 fresh basil (buy the plant – it will last longer if camping)

The trick is to lay everything out in a logical order.

Start with the bowls – large, or rimmed plates.
Next the pastas.
Then the meat choices.
Now you are ready for the sauces.
Finally the add-ons.
Last the cheese on top of everything.

For a large group arrange the set-up so it can be reached from both sides of the table.  Two lines – twice as fast!
