This chicken taco bowl recipe uses the underside of a muffin tin as a mold to bake cute little homemade “tortilla bowls.” The “tortilla bowls” are filled with a zesty chicken filling and topped like nachos. If you have 2 large muffin tins, you can make all 8 “bowls” at once. Bake them in the upper and lower thirds of the oven, rotating top to bottom about halfway through baking.
Preheat oven to 375 degrees F.
Heat tortillas until warm (see Tips). Coat each side of 4 tortillas with cooking spray. (Keep the remaining 4 tortillas covered.) Turn a 12-cup muffin tin upside down. Nestle a tortilla in the space between 4 cups to form a "bowl" (see Tips). Repeat with 3 more tortillas, making 4 bowls total. Bake until firm and beginning to brown, about 15 minutes. Transfer to a wire rack to cool. Repeat with the remaining 4 tortillas.
Meanwhile, toss chicken with garlic powder and salt in a bowl. Heat oil in a large skillet over medium-high heat. Add the chicken and cook, stirring, until it is no longer pink on the outside, about 3 minutes. Add salsa and cook, stirring, until the chicken is no longer pink in the middle, about 3 minutes more. Cover and remove from the heat.
Fill each tortilla bowl with about 1/4 cup of the chicken mixture. Top with 1 tablespoon each cheese and sour cream, 2 tablespoons each lettuce and tomato and a few olives.
