Baked Ziti always goes over well with my family and friends. The Swedish meatballs I totally cheated on, I bought them frozen from Ikea, bought the powder for the sauce and the lingonberry jelly too!
And another easy idea if you have a crock pot is pulled pork, you literally put it in the crock pot for 10-12 hours with 1 jar of your fav bbq sauce (I am not sure if you have a Famous Dave's near you but I used their Sweet and Zesty), after about 8 I used my fork to break the chunks into smaller pieces and removed the string from the pork and that was it - I left it on warm until I was ready to serve. It was a huge hit at my DDs Baptism and I live in NJ where BBQ is not huge like it was when I lived in TN. Oh, but have the butcher cut off the skin because that is the most disgusting thing ever - I actually did not eat it because of I cut it off myself!
