Preheat Your Oven: Start by preheating your oven to 375°F (190°C).
Prepare the Peppers: Carefully cut the tops off the poblano peppers. Remove the seeds and membrane for a milder flavor.
Mix the Filling: In a large mixing bowl, combine cooked rice, corn, black beans, and diced tomatoes. Stir until well mixed.
Stuff the Peppers: Take the prepared peppers and fill them generously with the rice mixture. Don’t be shy with the filling!
Arrange and Bake: Place the stuffed peppers in a baking dish, cover them with foil, and bake for about 25-30 minutes or until the peppers are tender.
Add Cheese (Optional): If you love a cheesy crust, remove the foil during the last 5-10 minutes, sprinkle with cheese, and allow it to melt beautifully.
Serve and Enjoy: Once they’re done, let them cool for a few minutes before serving. Enjoy the delightful textures and flavors of your homemade meal!
