Preheat your oven to 375°F (190°C). Pound the chicken between plastic wrap to an even thickness of about half an inch.
In a mixing bowl, combine taco seasoning with a little olive oil to create a paste. Rub this mixture over the chicken cutlets.
Place seasoned chicken in a baking dish. Pour salsa over the top to cover the chicken evenly.
Sprinkle shredded cheddar cheese over the salsa-covered chicken.
Cover with aluminum foil and bake for about 25-30 minutes. Remove foil and bake for an additional 10-15 minutes until cheese is bubbly and chicken reaches 165°F (74°C).
Remove from oven, let rest, and top with guacamole, sour cream, cilantro, jalapeno, and crushed tortilla chips.
