In a bowl, add shrimp, garlic powder, smoked paprika, Italian seasoning, salt and black pepper. Mix everything well.
In a cast iron skillet add 1 tablespoon of olive oil over medium heat.
Add shrimp and sauté for about 4 minutes or until shrimp is cooked through. Be careful to not overcook them, otherwise they will have a rubbery texture. Set aside.
To assemble the bites: Top each cucumber slices with a spoonful of the guacamole and a cooked shrimp. Garnish with additional fresh cilantro and squeeze some lime juice on top. Serve at room temperature.
