I hit up a couple grocery stores and ended up finding Bandt brand tiny, ready to eat farmers sausages that worked perfect.
Found through Pinterest, I ended up on tastykitchen.com.
As I mentioned, I didn't really find actual Smokies, but these were delish, and really, you could just use any cooked sausage cut up.
Amazing! The sauce/glaze is absolutely delicious, I will be making this to glaze a ham as well. Everyone loved these, including the kids, and I think these would make fabulous appetizers for any holiday.
