Turn those apples you've got sitting on your counter into a sweet-and-savory dinner recipe.
Scoop out the avocados from the skins into a small bowl. Mash in the oil and lime juice; season the guacamole with kosher salt. In a medium bowl, mix the apple, bell pepper, celery, vinegar, mint, cumin, and honey; season the salsa with kosher salt. Build the tacos with the tortillas, chicken, guacamole, salsa, and cheese. Drizzle with the sour cream.
