Preheat oven to 350°F
Combine your 4 cups oats, 1 tsp cinnamon, 1 tsp salt, and 1/2 tsp ginger in a large bowl. Set aside.
In a separate bowl, beat your 2 eggs and 3 cups of milk together until everything is evenly combined. Add your 1 grated apple, 1 1/2 cup grated carrots, 1/2 cup raisins, your juice and zest from 1 orange, 1/2 cup unsweetened apple sauce, 1/2 cup pecans, 1/2 cup maple syrup, and 2 tbsp flax meal. Stir until everything is evenly combined.
Add your wet mix to your dry mix and stir until the oats are completely covered and the add ins are evenly distributed.
In a baking dish sprayed with non-stick cooking spray, pour your combined oatmeal into the baking dish. Sprinkle with brown sugar if desired and place in the oven for 35-40 minutes. Your oatmeal should will be golden on top and slightly puffed from the oats absorbing the liquid.
Let rest for 10 minutes before cutting into 8 portions. Serve with peanut butter, or yogurt, or fruit.
