Preheat your oven to 375°F (190°C).

In a large skillet, melt the butter over medium heat. Add the diced onion and celery, cooking until soft (about 5-7 minutes).

In a large mixing bowl, combine the cooked bread cubes, sautéed vegetables, dried sage, dried thyme, and a pinch of salt and pepper.

Pour in the chicken or vegetable broth gradually, mixing until the bread is well-moistened but not soggy.

Lay a tortilla flat and spoon a generous portion of stuffing onto the center. Sprinkle with cheese, then roll tightly from the bottom up.

Place the rolled tortillas seam-side down in a greased baking dish.

Bake in the preheated oven for 20-25 minutes until the roll-ups are golden and heated through.

Meanwhile, prepare the creamy gravy by combining heavy cream and some broth in a saucepan over medium heat, stirring until heated through. Season to taste.

Once the roll-ups are cooked, remove them from the oven and drizzle with creamy gravy before serving warm.
