Where can I buy frozen bulk food besides Costco and sams?

We’ve got a small family reunion coming up and I was put in charge of meals. The cabin we’re staying in will accommodate all of us but the kitchen is just a normal kitchen so we’re going to be limited on what’s easy to whip together for a crowd of 15.

So I’m trying to find frozen things that are easy to pop in the oven, things like frozen omelettes, heck even pancakes..simple easy breakfast foods.

Any place you guys can think of that will have what I’m looking for?

So far I can find frozen omelettes but it’s a pack of 48 for about 100 bucks and that’s just too much food and price wise.
