This Shrimp Avocado Cucumber Appetizer is a fresh and flavorful bite-sized treat perfect for parties or light snacks. Juicy, Cajun-spiced shrimp are cooked quickly in butter and citrus, then paired with creamy green chili guacamole atop crisp cucumber slices, finished with a drizzle of tangy remoulade sauce and garnished with fresh chives for an irresistible combination of textures and flavors.
