This chicken omelette recipe is the perfect way to repurpose dinner leftovers. The cooked chicken paired with tomatoes, onion, and cheese will give you a filling and flavorful breakfast to kickstart your day.
Heat a non-stick pan to medium and drizzle with olive oil. Add the onion and mushrooms. Cook until the onion is transparent and the mushrooms are cooked through. About 5-10 minutes.
Add the rotisserie chicken to heat it up with the rest of the ingredients.
Crack the eggs in a mixing bowl and whisk until frothy. Add the sea salt, black pepper, and horseradish. Whisk to combine.
Pour the egg mixture on top of the chicken and vegetables and cover. When it is done it will be cooked through on the bottom and slightly runny on top.
Add the cheese all over the top and fold in half with the spatula. Transfer to a plate and serve with avocado and chives on the side.
