Ingredients
  

  • 1 spaghetti squash 2 - 2.5 lb, cooked and shredded - about 4 cups
  • 4 cups cooked chicken diced or pulled rotisserie
  • 2 tbsp avocado oil
  • 1/2 large yellow onion diced
  • 5 cups roughly chopped broccoli
  • 4 cloves garlic minced
  • 1 cup plain Greek yogurt
  • 1.5 cups cheddar cheese divided
  • 2 tsp salt
  • 1/2 tsp pepper

Method
 

  1. Preheat oven to 400F and grease 9x13 baking dish.
  2. Prepare your spaghetti squash according to this recipe, or however else you make cooked spaghetti squash. Prepare your chicken as well. I used rotisserie chicken for this and it worked great.
  3. In a large pan, heat avocado oil and onion over medium-high heat. After a minute, add in broccoli.
  4. Cook onions and broccoli for 6-7 minutes or until begin to tenderize, and then add garlic for last minute of cooking. Turn off heat.
  5. In a large bowl, add spaghetti squash, chicken, broccoli and onions, greek yogurt, 1 cup of cheese, salt, pepper, garlic powder, and onion powder. Stir until well combined.
  6. Add in whisked eggs and stir until everything is mixed together well.
  7. Pour into greased 9x13 baking dish. Top with remaining cheese.
  8. Bake for 45-50 minutes or until inside is set and bubbling.
  9. Let cool 15 minutes before eating.
