Preheat oven to 375 degrees F. Lightly oil a 9 x 13 baking dish or coat with nonstick spray.
In a small bowl, combine Dijon, mayonnaise and green onions; season with salt and pepper, to taste. Spread mixture on top half of dinner rolls; set aside.
Place bottom half of dinner rolls onto the prepared baking dish. Top with cranberry sauce, turkey, cheese and top of dinner rolls. Brush tops of dinner rolls with butter; sprinkle with poppy seeds.
Place into oven and bake until golden brown and toasted, about 15-18 minutes. Let stand 5 minutes.
