Slow cooker BBQ Beans and Polish Sausage

My best friend for forever is married to one of the pickiest eaters ever... (Love ya Bill!) Every once in a while she wants to strike out and be adventurous in her cooking, but between her husband and kids she has to hold back! So, when I got this email from her, I just started laughing... She was so excited - she tried a new recipe and EVERYONE in her family loved it! Yippee for her and for us too! She had to share the recipe that went over so well and you know that I had to try it and share it with you! I made this the other night and it was super yummy - I might have to just make the beans on their own sometime, that is how good they were!!
