- 30 lbs meatballs (in crock-pot)- 20 is plenty
- 18 lbs cocktail wieners (in crock-pot)- OK, 15 probably enough
- Fruit for trays (4 pineapples, 6 lbs strawberries, 6 lbs grapes, 6 lbs apples)-double the strawberries, be sure to dip the apples in orange juice to prevent the slices from browning, add a vanilla or maple yogurt dip with a little nutmeg or mace- 2-3 quarts
- Veggies for trays (3 lbs broccoli, 2 lbs celery, 3 lbs carrots, 2 lbs tomatoes, 12 cups ranch dressing)- maybe add a couple of cauliflowers for color
- 20 lbs cubed cheese- 12-15 plenty
- 8 lbs tortilla chips-OK
- 1 gallon salsa-OK

We have several people attending who are gluten-free, dairy-free, and/or vegan so I'm wondering if I need to serve hummus also or instead of salsa and perhaps a different type of chip to go with it?
hummus is a great addition and you can get really good gluten free rice and sesame crackers/chips

For dessert I've planned:
- 90 candy graduation lollipops (a Reese's cup topped with a square of chocolate)
- 96 pirouette cookies- you could double these
- 96 mini frosted cupcakes
Drinks:
- 192 (8 oz) bottles water
- cans of soda? juice boxes? how about lemonade or iced tea, or both? About 6 gallons total for tea, 2 unsweet, and 4 gallons lemonade
