Ingredients

  • 5 cups cooked brown rice
  • ¼ cup fresh chopped parsley
  • 8 cloves garlic minced
  • 8 oz mushrooms sliced
  • 1 large sweet potato diced
  • 1 cup plain nonfat greek yogurt
  • 1 ½ cups freshly grated parmesan cheese
  • 1 cup shredded mozzarella cheese
  • 1 cup shredded cheddar cheese
  • 10 oz frozen spinach
  • olive oil
  • salt and pepper
  • ¼ teaspoon onion powder

Instructions

  • Preheat oven to 425 degrees
  • Dice sweet potato and toss with ⅛ cup olive oil, ¼ teaspoon salt, ¼ teaspoon pepper, and ¼ teaspoon onion powder
  • Spread sweet potatoes out into one layer on a baking sheet
  • Roast at 425 for 15 minutes, then stir
  • Roast an additional 10-15 minutes, until fork tender
  • Cook brown rice according to package instructions (I used a rice cooker for convenience)
  • In a skillet, sauté mushrooms and garlic with 1 teaspoon of olive oil
  • Cook on medium high for around 10 minutes, or until mushrooms emit their liquid and start to cook down
  • Add frozen spinach and cover with a lid, until spinach thaws and breaks apart
  • In a large mixing bowl, combine mushroom mixture, brown rice, sweet potatoes, greek yogurt, parsley, cheddar cheese, and parmesan cheese
  • Salt to taste (I added 1 teaspoon of salt)
  • Transfer mixture to a 13 X 9 casserole dish
  • Top with mozzarella cheese
  • Bake at 400 degrees for 20-25 minutes, or until cheese is bubbly and beginning to brown
