Ingredients
Serves: 4 (2 peppers each)
- 1 lb 90% lean ground beef
- 1 15-oz can black beans, drained and rinsed
- 1¼ teaspoons salt divided
- Heaping ¼ teaspoon baking soda
- 8 large red, yellow, or orange bell peppers, tops and cores removed
- 3 tablespoons extra-virgin oil
- 1 medium yellow onion, finely chopped
- 3 cloves garlic, minced
- 1½ teaspoons chili powder
- ½ teaspoon ground cumin
- ¼ teaspoon dried oregano
- 1 (8-oz) can tomato sauce
- 1 cup cooked rice, quinoa, or any grain
- 1½ cups shredded Monterey Jack or Cheddar Jack cheese

Directions
- Preheat the oven to 425°F (220°C) and set an oven rack in the middle position.
- Tenderize the beef: In a medium bowl, using your hands, mash the beef with 1 teaspoon of the salt and the baking soda. Let sit for 20 minutes while you continue with the recipe.
- Line a 9 x 13-in (23 x 33-cm) baking dish with aluminum foil for easy clean-up, if you like. Place the peppers, cut side up, in the baking dish; drizzle with 1 tablespoon of the oil and sprinkle with the remaining ¼ teaspoon salt.
- Roast the peppers for about 20 minutes, until slightly browned and tender-crisp. A bit of liquid will accumulate in the bottom of the peppers; that’s okay.
- Meanwhile, heat the remaining 2 tablespoons of oil over medium heat in a large nonstick skillet. Add the onion and cook, stirring frequently, until soft and translucent, 3 to 4 minutes. Add the garlic and cook 1 minute more; do not brown. Add the ground beef mixture, chili powder, cumin, and oregano, and increase the heat to medium-high. Cook, breaking the meat up with a wooden spoon, until the meat is browned and almost cooked through, 4 to 5 minutes. Add the tomato sauce and bring to a boil; reduce the heat to medium-low and cook, uncovered, until the meat is cooked through, 2 to 3 minutes. Add the cooked rice and ¾ cup (90 g) of the cheese, and stir until melted. Remove the skillet from the heat.
- Remove the peppers from the oven and spoon the meat filling evenly into the peppers. Sprinkle with the remaining ¾ cup (90 g) cheese and place back in the oven. Roast for 10 to 15 minutes, until the filling is hot and the cheese is melted and bubbling, and serve.
