I regularly do appetizers for Christmas Eve, as people are in & out all day long.
This one was INHALED by the kids last year:
TACO DIP
1 (2 pound) loaf processed cheese, cubed
1 1/2 pounds ground beef
2/3 cup water
1 (1.25 ounce) package taco seasoning mix
1 (16 ounce) jar picante sauce (I used chunky mild salsa instead
Melt processed cheese in a slow cooker set for high heat. Stir occasionally to avoid burning.
Place ground beef in a large skillet. Cook over medium high heat until evenly brown. Drain beef, and mix in water and taco seasoning mix. Cook and stir 2 to 4 minutes.
Stir seasoned beef into the melted processed cheese. Mix in salsa. Cook and stir until well blended. Serve warm with corn chips.

Also did some commercial chicken tenders in the oven, served with ranch & BBQ sauce for dipping - kids liked that also.
For adults, I usually rely on the same old, same old: shrimp/cocktail sauce, meatballs (either in a swedish sauce or the infamous grape jelly sauce

)crudites, cheese, spinach dip...you get the idea.
