Ingredients
  

  • 1 tablespoon extra-virgin olive oil
  • 1 pound lean ground beef
  • 2 tablespoons tomato paste
  • 1 medium red onion thinly sliced
  • 1 large green bell pepper thinly sliced
  • 1 medium orange bell pepper thinly sliced
  • 1 medium yellow bell pepper thinly sliced
  • 1 tablespoon smoked paprika
  • 1 tablespoon Italian seasoning
  • 1 teaspoon garlic powder
  • 3/4 teaspoon salt
  • 1/2 teaspoon crushed red pepper
  • 1 (14.5-ounce) can no-salt-added diced tomatoes with basil, garlic, and oregano
  • 1 (8.8-ounce) package precooked microwaveable brown rice
  • 1/2 cup unsalted beef broth
  • 1 tablespoon red-wine vinegar
  • 1 cup shredded low-moisture part-skim mozzarella cheese
  • Chopped fresh oregano for garnish (optional)

Instructions
 

  • Preheat the oven: Set your oven to 400°F so it’s ready when you need it.
  • Cook the ground beef: Heat the olive oil in a large ovenproof skillet over medium-high heat. Add the ground beef and cook, stirring often to break it up, until it’s no longer pink, about 5 minutes.
  • Add tomato paste: Stir in the tomato paste and cook for 1 minute, letting it caramelize slightly to deepen the flavor.
  • Sauté the veggies: Add the onion, bell peppers, smoked paprika, Italian seasoning, garlic powder, salt, and crushed red pepper. Cook, stirring often, until the vegetables are tender-crisp, about 6 minutes. Remove the skillet from heat.
  • Combine the ingredients: Stir in the diced tomatoes, precooked rice, beef broth, and red-wine vinegar until everything is well combined.
  • Bake with a lid: Cover the skillet with a lid or foil and bake in the oven for about 10 minutes, or until the rice is tender.
  • Add cheese and finish: Remove the lid, sprinkle mozzarella cheese evenly over the top, and bake uncovered for an additional 8 minutes, or until the cheese is melted and bubbling.
  • Garnish and serve: Sprinkle with fresh oregano if desired, and serve immediately!
