Paleo Shepard's Pie

1 tbsp coconut oil (more will be used to grease the baking dish)
2 pounds ground lean turkey
1 onion diced
3 cloves garlic minced
2 stalks celery chopped
2 tsp(s) Thyme
1 tbsp Oregano
1 tsp crushed red pepper
1 tsp pepper (more to taste)
1 bag mixed frozen vegetables (carrots, peas, green beans) or any combo of chopped veggies will work)
1 cup fresh or frozen chopped spinach
1/2 cup organic broth, (the best would be to keep broth from chicken or beef that was cooked on a previous day, store in a sealed container for up to 4 days in the fridge), if you do not have broth or prefer not to use it, water will work too
1-2tsp Arrowroot Powder, add 1 tsp at a time, to thicken the broth
