Sprinkle the cotija evenly over the top of the squash and heat pan in the oven until the cheese is just lightly golden brown. Remove from oven. Immediately portion into a serving dish and squeeze the fresh lime over the top of the squash then sprinkle the cilantro over the top of the squash. Serve immediately.
