Roast the peppers by placing them over a stovetop gas flame, turning them frequently with tongs until all sides are charred black, about 7 – 10 minutes.
With a vegetable peeler, peel the squash, then cut in half and remove the seeds. Cut the squash into 1/4-inch pieces.
Heat the oil in a large skillet or sauté pan over medium-high heat. Add the onions and cook, stirring, for 3 minutes. Add the squash, salt, and chili powder, and stir well. Cover and cook until the squash is almost tender, stirring occasionally, about 10 – 12 minutes.
Place the blackened peppers in a plastic or paper bag, and let rest until cool enough to handle, about 15 minutes. Stir in chilies and cook, uncovered, for 3 minutes. Sprinkle the cheese over the vegetables and cover. Lower the heat to medium-low and cook until the cheese is melted, about 2 minutes.
Serve hot out of the pan.
