Angela, if this is only 65 people, this menu would benefit from a little work, especially since you are doing it all yourself.
Spinach alfredo tortellini,
Penne ala vodka,
Wild rice pilaf,
Herb roasted new potato,
One or 2 too many too many starches. The tortellini has to be cooked at the last minute; skip either it or the penne. I would also skip the potatoes, none of the meats really call for potatoes.
For 65, I would do 5-6 pounds of rice and 6-8 pounds dry penne, or equivalent in tortellini.
meatball in marinara sauce,
Chicken marsala,
citrus glazed salmon,
sausage and pepper,
Too many meats. For 65, 2 or at most 3. I would skip either the meatballs or the sausage and peppers. 1 pound whole boneless chicken breast in small pieces, for 4 PLUS 1 pound salmon per 5. If adding the meatballs or sausage and peppers, both the above plus 1 pound beefy choice per 5.
When you have more meats, people take more, and usually some of each.
salad and fresh breadstick. Fine, do 2/3 the amounts for 100 from the plan for 100 list.
