1. Preheat the oven to 400°F (200°C).
2. Cook the bacon in a skillet over medium heat until crispy. Transfer to a paper towel-lined plate to drain excess fat.
3. Cut the avocado in half, remove the pit, and scoop out the flesh. Mash it in a bowl and set aside.
4. Wash and dry the lettuce, then chop it into thin strips.
5. In a small bowl, mince the garlic and mix it with the olive oil to make a garlic oil.
6. Place the bread slices on a baking sheet and brush them with the garlic oil. Toast in the preheated oven for 5-7 minutes or until golden brown.
7. Spread the mashed avocado evenly on the toasted bread slices. Top with chopped lettuce and crispy bacon.
8. Serve immediately and enjoy your Avocado Bacon Garlic Toast!
