Preheat your oven to 425 degrees Fahrenheit.
Place your street taco corn tortillas on a baking sheet.
Brush or spray both sides of each tortilla with olive oil.
Add a heaping tablespoon of shredded chicken mixture into each tortilla, followed by a generous tablespoon of shredded cheese.
Bake the filled tortillas for about 2 minutes, just until the cheese melts.
Return the folded tacos to the oven and bake for another 12–15 minutes until they are crispy on the outside.
Serve your mini tacos with sour cream, salsa, and fresh cilantro on top.
