Add the softened cream cheese, greek yogurt, taco seasoning, lime zest, and lime juice to a large bowl. Mix until well combined. 

Transfer the dip base to your serving bowl and then top with shredded cheddar cheese, iceberg lettuce, Roma tomatoes, avocado, and jalapeño.

Serve at room temperature with tortilla chips for dipping. Store any leftovers in an airtight container in the fridge for up to two days.
