Line a large, rimmed baking sheet with parchment paper or a Silpat® baking mat. Arrange the corn tortilla wedges on the prepared baking sheet without overcrowding. Sprinkle both sides with garlic powder and sea salt, to taste, and place in pre heated oven. Bake until crispy and golden brown, approximately 8-10 minutes, before removing from oven. For best results, stir tortilla chips once halfway through baking.
