Avocado toast is a great breakfast option because it is quick and easy to make, and it provides a good balance of healthy fats, protein, and carbohydrates to start your day off right. Avocados are rich in heart-healthy monounsaturated fats, which can help lower cholesterol levels and reduce the risk of heart disease. In addition, avocados are a good source of fiber, potassium, and vitamins C, K, and B6.
