Preheat oven to 400°F. Line a half sheet pan with parchment paper or lightly oil it.
Shred the turkey into bite-sized pieces and lightly warm it. Warm the stuffing as well.
Spread tortilla chips in a single layer over the prepared pan.
Evenly top with turkey, stuffing, shredded cheese, and jalapeño slices (if using).
Bake for 5–6 minutes, until heated through and the cheese is melted. If needed, switch the oven to broil for 1–2 minutes to fully melt the cheese.
Drizzle with cranberry sauce and serve immediately.
