A 400-degree oven is required. Put parchment paper on a baking sheet and set it aside.
Add ground beef, taco seasoning, tomato paste, 2 tablespoons chopped chilies, egg, breadcrumbs, and cilantro to a large bowl and combine well. Using the prepared baking sheet, form the meatballs into 2-inch balls.
Ensure that the dish is cooked through by baking it for 15-20 minutes. Make a scoop out of corn chips and place each meatball in it. Add cheese, guacamole, pico de gallo, and chopped cilantro. Sour cream should be served on the side.
