K.,
Breakfast casseroles are always a hit. Try www.allrecipes.com for some good recipes. They are all rated, so you will know if they are good ones.
Other things I've had at brunch: coffee cake, mixed fruit, mimosas (OJ and champagne). For lunch type stuff: cheese and crackers, Ham and rolls, mostacolli or pasta salad.
Also, something that is very easy that my mom and I always get requests for is the following:
1 pkg cream cheese
1 pkg ground sausage (like Jimmy Deans in the breakfast sausage area)
1 pkg crescent rolls
Brown the sausage. Mix with the cream cheese till creamy. Roll out the crescent rolls flat. Put the mixture in the center of the crescent rolls. Pull together in pinch down the center and fold in the sides. Bake at about 350 degrees until browned on top. Let cool and cut in slices.
