Make Ahead - You can prep everything ahead and simply warm the beef to serve or keep the beef warm in a slow cooker with 1/4 cup of water so that it's ready when you are. These are best constructed just before serving to prevent soggy chips.
Serve with Utensils - This way you can get a little of everything in each bite, without making a mess. One of the most frequently-asked questions I receive: "Where are those cute little wooden forks from?" I love these disposable wooden utensils. So much cuter than plastic!
