Best 7 Layer Dip

This is always a crowd pleasing appetizer. It's a layered dip that is eaten with tortilla chips. It is made differently from person to person but this is how I like to make it.

Recipe:
30 oz refried beans
about 2 c guacamole or
3 or 4 avocados mashed with some sour cream
16 oz container sour cream
1 packet taco seasoning
jar of salsa
shredded cheese
sliced olives

I don't have exact measurement for this. Just layer ingredients according to how much you want. In a 9x13 pan layer refried beans on the bottom. Then prepared guacamole, or mash up the avocados with sour cream and layer on the beans. Then mix sour cream with about 3/4 packet of taco seasoning. Layer the sour cream mixture on the guacamole. Then layer the jar of salsa. Sprinkle shredded cheese all over the top and then sliced olives. Keep refrigerated until serving. Serve with tortilla chips.
