Place shrimp in a large mixing bowl and pat dry with paper towels. Add lemon juice, creole seasoning, salt, cayenne and 1 tbsp olive oil. Stir well to combine. Heat a large heavy pan over medium/high heat with 1 Tbsp olive oil. Once the oil is hot, add shrimp in a single layer and saute 2 min per side or until cooked through. How to Make Avocado Spread & Assemble: In a small bowl, mash together Key Lime Rum Cream, avocado, 1/4 tsp salt, and lime juice until creamy. Divide the avocado mix over 20-22 cucumber slices. Squeeze fresh lime juice over the shrimp avocado bites and garnish with more finely chopped cilantro. If not serving right away, cover and refrigerate up to 4 hours before serving.
