Sure! Instead of rice, you can substitute it for an equal quantity of cauliflower rice.

How to make a Spinach and Feta Casserole with Rice and Ground Beef
Special Equipment:
None needed! Here are some of the tools that I used though!
Ingredients:
1 lb ground beef
1 medium onion, diced
salt and pepper to taste
1 teaspoon of garlic powder
1 tsp dried oregano
2 cups of cooked rice
2-12oz packages of frozen spinach (You want about 24 oz of frozen spinach, slightly more or less is fine depending on what size packages are available for you)
½ cup milk (we used almond milk)
1 cup sour cream
½ cup feta cheese
½ cup mozzarella
Preheat the oven to 350 degrees. In a large skillet, saute the diced onion and ground beef until the beef is fully cooked. Season the meat lightly with salt and pepper. Defrost the frozen spinach according to the package directions. Squeeze out all of the liquid to the best of your ability.
Take the skillet off of the burner. Add the rest of the ingredients to the skillet and mix until incorporated. Alternatively, you can mix it in the baking dish that you will be cooking it in, or pour it all into a large bowl so that you can ensure that it’s all mixed.
Pour the mixture into a 9×13 baking pan and spread it out evenly. Bake at 350 for 30-45 minutes or until the mixture is bubbly and the edges are getting a bit crispy. Serve hot. Top with fresh diced tomatoes if you like them! Have you ever had a spinach casserole that you enjoyed? What do you usually serve it with? Let us know in the comments below!
