My mom's side of the family had some German in the family. We don't really celebrate things German. Being German is still part of my heritage and culture. My dad's side of the family is also part native american along with my mom's.
My mom makes a homemade traditional thanksgiving meal. The main part of the meal is the turkey and it takes a day to make so we always start it the day before. I don't quite know the recipe but this link shows you how to do a very traditional turkey.
On my dad's side of the family my grandma makes monkey bread every Christmas morning. It has been a tradition ever since I was a baby. We eat it for breakfast with a fruit usually.
My parents influence what I eat and they make it so that I have good food they cook it in the kitchen and the kitchen is the one thing in are house that has to be spotless at all times in order to cook.
I would eat tacos not because of my ethnicity but because with tacos you can pretty much add whatever you want this video is not how I make tacos but it explains and shows how you can add whatever condiment you want.
The top Germany foods are listed in this video I personally don't like these foods but part of my culture does.
