I LOVE DEVILED EGGS. They are my FAVORITE! But for some reason out here in Wyoming, they think "deviled eggs" are just whipped yolks with mayo and sugar added and
maybe a dash of paprika.

It's a LIE.
Lol, I kind of just dive in with substitutions and it usually works!

I will keep your mom in mind for if I find a struggle with it though.
Awe, you're so sweet. :')
Lol, the movie is definitely exaggerating a little bit.

The vibes are the same, though! It does depend on the holiday, too.
The general vibes that are the same are "OPA!", lots of meat, insisting you eat the food, plenty of (responsible) alcohol enjoyment, welcoming in literally everyone there as "family", sometimes the dancing. Usually during Thanksgiving and Christmas a sizeable group of men will go outside and smoke very fancy special cigars and pipe tobaccos. During Easter (we call it Pascha in the Orthodox church and celebrate it very differently than the Western culture) we all get up to go to church at midnight the night before Easter proper (which is not based on the Western calendar. Last year it was the same day as Western Easter, but this year it's a month or two earlier). It's a huge symbolic service with hundreds and hundreds of candles! Everyone will have been fasting for 40 days for Lent (basically eating like vegans more or less, but we don't consume "substitutes" for any of that food), so after the service we gather together at like 1 AM and have a literal FEAST. Music, Greek dancing, more radiating joy than I've ever seen from any human ever, this year there was a shots bar (again, responsibly enjoyed)??

They usually do something like make a lamb centered meal, but a lot of people will bring a huge variety of their own food. We brought a lot of cheeses and some meats. A friend of ours has a smoker, so he spent all day smoking all sorts of meats, and baking others. I think one thing he brought was marinated steak wrapped in bacon and stuck on a stick. Like meat lollipops.

Both of the priests present ended up sitting at our table, I guess we just had the best food, haha! Everyone shares if they bring something extra. Our friend was running around telling people to take and eat, and his stuff was a huge hit. Everyone goes home at like 3 or 4, then there's a service at 11am that... Ehhh, definitely not everyone makes it to.

But yeah, the Resurrection is basically celebrated as the most important thing ever and Pascha/Easter is now my favorite holiday! I think it used to be Christmas. I still LOVE Thanksgiving and Christmas though, so many good memories and so many amazing new ones to make with my church family.
Thanksgiving is in the middle of the Nativity Fast (or, Advent), so it's also a much appreciated feast, while Christmas is at the very end of that fast. It all makes these holidays so much more special for us!
