Welcome to DC, tipplej! I'm so glad you are taking us along on your eating adventure. Might inspire me to try some "exotic" dishes. The one piece of advice I can offer is something I learned that makes things run a bit more smoothly for me. Read your recipe several times before you start, measure out and line up all your ingredients, and double-check each measure to make sure it's what you need. (Lesson learned after one, very embarrassing pumpkin pie made with no sugar...the year after I admonished my Mom for forgetting the sugar.)
I come from Polish stock. I grew up eating both foods that have made it into the mainstream and foods that are decidedly old-world. For Polish foods you can't go wrong with a smoked sausage like kielbasa, served up along side a pile of pierogi sauteed in butter and onions. Every culture has pierogi, they just call them by different names: ravioli, pot stickers, etc. All variations of yummy, filled noodle dough. Pierogis aren't hard to do - I've done it once and wonder why I haven't made them since. If you're interested, I found a simple tutorial; links to the recipe variations are after the author's story.

Or think "Hot Dog". Those wieners are served all over the country, but it seems like every region has their own style. This article from "Delish" offers up ten different variations. I found other sites, but this one seemed the easiest to navigate. Whatever you pick for the United States, have fun and enjoy!
