Preheat your oven to 400°F (200°C). Slice a baguette into ½-inch thick pieces and arrange them on a baking sheet. Drizzle olive oil over each slice, ensuring they're well-coated, then bake for 8-10 minutes until golden brown and crisp.

Heat a tablespoon of olive oil in a large skillet over medium heat. Add the minced garlic and sauté for about 30 seconds until fragrant. Introduce the shrimp, seasoning with paprika, cumin, salt, and pepper. Cook for 4-5 minutes until the shrimp are opaque.

Slice a ripe avocado in half, remove the pit, and scoop the flesh into a bowl, mashing it slightly. Add lime juice and mix.

Spread a layer of mashed avocado on each crostini, then spoon the shrimp mixture on top, distributing it evenly.

Drizzle a touch more lime juice over the finished crostini before serving.
