Mix all ingredients together. On a large plate or serving platter, smooth bean mix into a 10-inch circle using a rubber spatula.
Salsa & Cheese Layers
Optional: Drain the salsa in a colander to get rid of excess juice.
Spread over beans, leaving some of the bean mix just showing around the edges.
Spread cheese over salsa, repeating the layered look.
Meat Layer
Cook ground beef with taco seasoning, breaking it up as you go. Cook until meat is no longer pink. Drain grease.
Layer over cheese.
Guacamole Layer
Make guacamole (if you haven’t already). Spread over meat layer.
Spiderweb
Fill a piping bag (or ziploc with one corner cut off) with sour cream. Pipe concentric circles over the platter, then add the straight lines (you might want to practice this on a spare plate or piece of plastic wrap first).
Decorate with at least one toy spider. Add tortilla chips around the edge of platter.
