What cut are you thinking of for the beef?
I find bottom or top round works well, but I yield about 80% for the most part.
Sammie and a half is a good average with 3 sides.
75 X 5.33 = 400 Oz
400 / 0.8 = 500 Oz
500 / 16 = 31.25 lb
So if you're cooking 40 lbs you'll have enough for an extra 21 sammies.
