Preheat your oven to 400°F (200°C). Slice a baguette into ½-inch thick pieces and arrange them on a baking sheet. Drizzle each slice lightly with olive oil, ensuring they are evenly coated. Bake for about 10 minutes, or until they turn golden brown and crispy.

While the crostini bakes, heat a tablespoon of olive oil in a skillet over medium heat. Add minced garlic and sauté for about 1 minute until fragrant. Then, add your seasoned shrimp and cook for approximately 5 minutes.

In a medium bowl, scoop out ripe avocados and mash them with lime juice, salt, and pepper to taste until smooth.

Once the crostini are out of the oven, spread a generous layer of the avocado mixture onto each toasted slice. Top with a piece of shrimp and serve immediately.
