Cook and crumble the ground beef and season with cumin, cayenne pepper, coriander, paprika, red pepper flakes, and a pinch of salt. Make far enough ahead to let cool completely.
In a food processor, combine the avocados, sour cream, Roma tomato, red onion, 1-2 green onions, lime juice, lemon juice, jalapenos, garlic powder, cumin, and cilantro. Blend until smooth.
In a small bowl, mix together the cream cheese, chipotle peppers in adobo sauce, and fresh parsley until no chunks of cream cheese remain.
First layer: Spread a thick layer of the chipotle cream cheese across the bottom of the pan.
Second layer: Add the cooked ground beef on top of the cream cheese.
Third layer: Spread the refried beans, if using, across the top of the taco meat.
Fourth layer: Then sprinkle half of the colby jack cheese on top of the beans, along with some fresh parsley.
Fifth layer: Spread a smooth layer of the avocado sour cream mixture across the top of the cheese and beans.
Sixth layer: Add the diced tomatoes, remaining chopped green onions, and any leftover parsley in a thin layer.
Seventh layer: Spread the shredded iceberg lettuce evenly across the top, followed by the remaining colby jack cheese.
Serve with tortilla chips, crostinis, veggies, and anything else you can dip. Enjoy!
