How to make this breakfast chicken hash
The Whole30 breakfast recipe could not be easier to make. To start, add your potatoes and garlic to salted water and cook them until tender. Mash them with the chicken broth and set aside.
If you have some leftover mashed potatoes, you can use those instead!
Heat the olive oil in a nonstick skillet over medium heat. Add the peppers, shallots and mushrooms and cook until they are tender. Then add the chicken and stir to combine.
Once that’s all combines, add the mashed potatoes and cook, stirring often. I like to let it sit a bit and then use a spatula to turn it so that the potatoes brown slightly.
Serve immediately and garnish with sliced avocado and fresh chives.
If you want something even a bit more hearty, try adding a poached egg on top and half of a grapefruit. This gives you a bit more protein and is perfect for brunch.

The flavors of this leftover chicken hash recipe are fresh and tasty! Every bite of this amazing breakfast chicken hash is bursting with flavor. It is the ultimate “comfort food” clean-eating recipe.
SUBSTITUTION TIP: How to make this recipe fit the Paleo diet? Sub out the white potatoes for sweet potatoes, and you are good to go!
