Appetizers and Food Menu....

It should be, our only appetizers are going to be bruschetta and a fig crostini. Our dinner will also be buffet style so people can eat as much as they want - just make sure you won't run out of food

AGREE with this.

But it's not enough for a 100+ guest count

The selection has nothing to do with your guest count. That menu is perfectly fine for 100+ people. Many catering menus online offer less selection than that regardless of formality or size.

Do you have vegan/vegetarian guests? If they wouldn't be able to eat much...and nothing from your cocktail hour. Consult with your caterer about adding a non meat/dairy appetizer and side dishes such as a veggie/hummus display or veggie spring rolls along with a vegetarian option.

If they have all food types covered..they are missing vegetarian/vegan options so maybe they don't have any vegetarian guests..what is your reasoning that the caterer can't feed 100+?

What is offered is very generous for a plated or buffet (can't tell from the description which they chose). Choice of 2 meats plus 4 sides and rolls is more food than most caterers offer for any size group. The 2 meat only appetizers will leave any vegetarians hungry though.

. I've never said a caterer couldn't feed 100+, I was talking about the cocktail hour, because she was planning on having meatballs and a charcuterie board, I think she should add at least one vegetarian option.

I wasn't aswering not about the dinner. I should have mentioned it. My bad!

Yes people will definitely be hungry during the cocktail hour with alcohol flowing..making for drunk guests. Add a least more appetizers..fruit/veggies/hummus, chips and dip, a couple non beef passed apps. Mini quiches, spanakopita, tea sandwiches, anything.

I would have more options during cocktail hour. You want to make sure that you have enough food so that people aren't drinking a whole bunch and are drunk by the time your reception starts. I would recommend having a veggie or fruit plater especially if you have anyone that is a vegetarian/vegan.
