In a saucepan over low heat, warm the refried beans, diced green chiles, and cumin, stirring to combine.
Spread the refried beans on the bottom of a platter, 9x13-inch glass dish, or divide among individual jars.
Sprinkle the cheddar cheese evenly over the beans.
Dollop with sour cream and spread it into an even layer, being careful not to disturb the cheese underneath.
Mix the mashed avocados with lemon juice if using instead of guacamole.
Dollop the avocado mash or guacamole over the sour cream and spread it into an even layer. Sprinkle with Monterey Jack cheese, followed by green onions and chopped olives.
Top with pico de gallo and/or chopped tomatoes, diced jalapenos, and chopped cilantro if desired. Serve with your favorite tortilla chips.
This dip looks absolutely beautiful served on a platter!
My Mama always put this dip in a glass dish so you could see all the layers!
