Ingredients:

• 4 large poblano peppers
• 8 ounces queso fresco or Monterey Jack cheese, cut into strips
• 1 cup all-purpose flour
• 4 large eggs, separated
• 1 teaspoon salt
• Vegetable oil for frying
• 2 cups tomato sauce (salsa roja)
• Optional toppings: sour cream, chopped cilantro, diced onions

Instructions:

1. Preheat the broiler in your oven. Place the poblano peppers on a baking sheet and broil them until the skins are blistered and charred, turning them occasionally to ensure even charring. This process usually takes about 5-7 minutes.
2. Transfer the charred peppers to a bowl and cover them with a clean kitchen towel or plastic wrap. Let them steam for about 10 minutes. This will make it easier to remove the skins.
3. After steaming, gently rub the peppers to remove the charred skins. Make a lengthwise slit on each pepper, being careful not to cut all the way through. Remove the seeds and membranes from the peppers.
4. Stuff each pepper with strips of cheese. You can use queso fresco or Monterey Jack cheese, or any other melting cheese of your choice. Gently close the peppers to seal in the cheese.
5. In a shallow dish, whisk the egg whites until stiff peaks form. In a separate bowl, whisk the egg yolks with salt until well combined.
6. Place the flour in a separate dish. Take each stuffed pepper and coat it in flour, shaking off any excess. Then dip the pepper into the beaten egg yolks, followed by the whipped egg whites, ensuring the pepper is evenly coated.
7. In a large skillet, heat vegetable oil over medium heat. Carefully place the battered peppers in the hot oil and fry them until golden brown on all sides. This usually takes about 4-5 minutes per side. Transfer the fried peppers to a plate lined with paper towels to drain excess oil.
8. In a separate saucepan, heat the tomato sauce (salsa roja) over medium heat until warmed through.
9. Serve the Chiles Rellenos hot, topped with warm tomato sauce. You can also garnish them with sour cream, chopped cilantro, and diced onions if desired.
