Slice cucumbers into ½ inch slices and core with the tip of a knife to make a little cup. Flip them over and lay them on a paper towel to drain off excess liquid.
Mince green onions and garlic. In a bowl, whisk together softened cream cheese, garlic, green onions, heavy cream, and salt until combined. Transfer into a baggie and cut off a small bit of one corner to make a piping bag.
Toss shrimp in Cajun seasoning and sauté in a frying pan until done. Place on a plate and set aside to cool.
Pipe a little cream cheese into each cucumber. Then top each one with a cool shrimp, followed by a tiny drop of sriracha and cilantro leaf for garnish. Place onto your favorite serving tray and enjoy your next party.
