1. Toast the slice of whole-grain bread until golden brown.
2. While the bread is toasting, cut the avocado in half, remove the pit, and scoop the flesh into a bowl.
3. Add lemon juice, salt, and pepper to the avocado, then mash it with a fork until smooth or to your desired texture.
4. Spread the mashed avocado over the toasted bread.
5. Add any optional toppings you like, such as sliced cherry tomatoes, radishes, or a poached egg.
6. Serve immediately and enjoy your nutritious meal!
