Trim ends off cucumbers. Split each cucumber in half lengthwise. Scoop out center of cucumbers, leaving a 1/4- to 1/2-inch-thick shell. Cut into 24 (1 1/2-inch-long) pieces.
Reserve any remaining cucumber for another use.
1 cup of Greek yogurt
Prepare 1/4 cup chopped red onion.
Combine yogurt, salmon, and onion in a food processor; process until almost smooth, scraping sides of bowl as needed. Spoon 1 teaspoons salmon mixture into each cucumber piece.
Sprinkle with dill for a more finished look.
This is definitely one of my favorite appetizer since I am smoked salmon and greek yogurt lover!
