Preheat the oven to 400°F (200°C). Slice the baguette into half-inch thick pieces.

Brush each piece of bread with olive oil and arrange on a baking sheet. Bake for 8-10 minutes until golden brown.

In a skillet, heat olive oil over medium heat and sauté minced garlic for 1-2 minutes.

Add shrimp to the skillet and season with smoked paprika, cumin, salt, and pepper. Cook for 3-4 minutes until shrimp are pink.

In a bowl, mash ripe avocados with lime juice, salt, and pepper until smooth.

Spread the avocado mixture over the crostini, then top each with sautéed shrimp.

Serve immediately, garnished with lime wedges or fresh herbs if desired.
