Ingredients

Scale
  • 1 lb (450g) ground beef
  • 1 medium onion, chopped
  • 2 cloves garlic, minced
  • 1 cup diced tomatoes (canned or fresh)
  • 1 cup frozen mixed vegetables or chopped fresh vegetables
  • 1 cup cooked rice or pasta

  • 1 tbsp olive oil
  • 1 tsp dried oregano
  • 1 tsp dried basil

Instructions

  1. Heat the olive oil in a large skillet over medium heat. Add chopped onion and sauté until translucent. Add garlic and cook for another minute until fragrant.

  3. Stir in diced tomatoes, tomato paste, and mixed vegetables. Let simmer for 5-7 minutes to meld flavors.
  4. Mix in cooked rice or pasta until well combined. Adjust seasoning if needed.

  6. Bake in a preheated oven at 375°F (190°C) for 20-25 minutes until cheese is bubbly and golden brown.

Notes

  • You can substitute ground turkey or chicken for the beef for a healthier option.
  • For extra flavor, add sliced mushrooms or bell peppers.
  • Use your favorite cheese for different flavor profiles, such as Monterey Jack or pepper jack.
  • Leftovers can be stored in an airtight container in the refrigerator for up to 4 days. Reheat in the microwave or oven.
