Notes
Tips and Substitutions
Cut the cucumber in half, then use a regular tablespoon to scoop out the center of the english cucumber.
When filling the cucumbers, place a sandwich baggie in a glass much and transfer the cream cheese mixture to the baggie. Snip an end off the corner of the baggie and pipe the stuffing into the hollowed out cucumber.
Instead of cutting the cucumber in half, cut them in slices and spread the cream cheese mixture on top then top with the toppings.
Instead of topping the cucumber appetizers with salmon, cut the salmon up in pieces and stir it into the cream cheese mixture to stuff the cucumber with.
