Ingredients
Here's what you'll need to create this mouthwatering dish:
- Leftover prime rib, thinly sliced
- 1 large onion, thinly sliced
- 1 green bell pepper, thinly sliced
- 1 large tortilla (flour or whole wheat)
- 2 cups shredded provolone or cheddar cheese
- 2 tbsp butter
- Salt and pepper, to taste
- Optional: 1 tbsp chopped fresh parsley for garnish
Instructions
Preparation
Start by prepping your ingredients. Thinly slice the leftover prime rib, onion, and green bell pepper. Shred the cheese if it's not already. Have everything ready to go, as the cooking process moves quickly.

Cook the Vegetables
In a large skillet, melt the butter over medium heat. Add the sliced onion and bell pepper, cooking until they soften and begin to caramelize, about 5-7 minutes. Season with salt and pepper.
Assemble the Quesadilla
While the vegetables are cooking, place the tortilla in a separate large skillet over medium heat. Sprinkle half of the shredded cheese evenly over one half of the tortilla. Top the cheese with the sliced prime rib and the cooked vegetables. Sprinkle the remaining cheese over the top.
Using a spatula, carefully fold the tortilla in half, covering the filling. Let it cook for about 2-3 minutes, or until the bottom half is golden brown and crispy. Then, using a large plate or cutting board, carefully flip the quesadilla over and cook the other side for another 2-3 minutes.

Serve
Once both sides are crispy and golden, transfer the quesadilla to a cutting board. Let it cool for a minute, then slice it into wedges. Garnish with chopped fresh parsley, if desired, and serve immediately.
