No many recipes that are American, but I would suggest for a larger crowd
Barbaque Spareribs, or country style, depending on how many. but you could
cook them inside and par boil and then bake in oven with pineapple on them
with some sauce.
I think that would go over well as they are tender. Baked beans goes well with them
and good ole american Potato salad ,or even amish Potato salad.
stuffed shells is also a great idea with a nice ceaser salad and garlic bread.
its hard to really say these are just American dishes, because I dont know when
they came about, but these are some of the things eaten here, so when they
were created who knows, I dont really think we have true american dishes
because everyone came from europe and other countries and most of what we
eat are combined dishes .
if anything is American is the good ole hotdog. dont think you want to serve that
unique dish

lol less your heading for a baseball game afterwards
