Chicken Chilaquiles Casserole

Adjust the oven racks to the upper-middle and lower-middle positions and heat the oven to 350 degrees. Spread the tortilla wedges on 2 rimmed baking sheets. Lightly coat both sides of the tortilla with vegetable oil spray.

Bake the tortilla wedges until they are lightly browned and begin to crisp, 8 to 12 minutes. Flip the tortilla wedges and continue to bake until the chips are fully toasted, 8 to 12 minutes longer. Set the tortilla wedges aside and turn the oven to 500 degrees.

Combine the poblano chiles, 1 cup of the onions, Melt®, and 1/8 teaspoon salt in a 12-inch skillet. Cover and cook over medium-low heat until the vegetables are softened, 8 to 10 minutes. Uncover, increase the heat to medium-high, and continue to cook, stirring occasionally, until the vegetables are lightly browned, 4 to 6 minutes longer.
