Ingredients
  

  • 1 cup gluten-free crispy onions store-bought or homemade
  • 2 tablespoons olive oil
  • 1 pound fresh green beans trimmed
  • 2 cups sliced mushrooms
  • 1 ½ onions chopped, divided
  • 1 cup mushroom broth
  • ½ teaspoon dried thyme
  • 1 teaspoon garlic powder
  • 1 teaspoon dried parsley
  • Salt and pepper to taste
  • 2 cups coconut creamer
  • 2 cups fresh spinach
  • 1 can of tuna drained
  • 2 cups cooked rice
  • 1 cup Cheddar cheese (shredded, dairy free) Optional

Instructions
 

  • Preheat oven to 375°F.
  • Bring a large pot of salted water to a boil. Add the green beans and blanch for 3 minutes. Drain and set aside.
  • In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add 1 cup of the chopped onions and sauté for 3-4 minutes until softened.
  • Add the mushrooms and sauté for another 5 minutes until they start to release their moisture.
  • Pour in the mushroom broth, thyme, garlic powder, parsley, salt, and pepper. Simmer for 5 minutes.
  • Add the coconut creamer and simmer for another 5 minutes until the sauce thickens slightly.
  • Spread the cooked green beans in a 9x13-inch baking dish.
  • Pour the mushroom-onion mixture over the green beans.
  • Add the cooked rice, spinach, and tuna, gently mixing them into the casserole.
  • Sprinkle shredded cheddar cheese evenly over the top.
  • Bake for 15-20 minutes, or until the casserole is bubbling and the cheese is melted and lightly browned.
  • While the casserole is baking, heat the remaining tablespoon of olive oil in a small skillet over medium heat. Add the remaining ½ onion and sauté for 10-12 minutes, stirring occasionally, until the onions are caramelized and crispy.
  • Remove the casserole from the oven and top with the crispy onions. Serve immediately.
