In a small pot, combine the oats and chicken broth over medium-high heat.
Once it comes to a low boil, reduce the heat and let simmer until it reaches your desired thickness. Stir occasionally until the oats are cooked through and creamy.
Remove the pot from the heat and pour the oatmeal into a bowl.
To prepare the toppings, cook the egg how you desire. Heat the chicken sausage in the air fryer or according to package instructions. Slice your tomatoes and avocado.
To assemble the bowl, layer your egg, sausage, tomatoes, avocado, and arugula on top of the oatmeal.
Sprinkle with everything bagel seasoning and enjoy!
