Slice the cucumbers as thin as you can with a mandoline slicer.
In a small pan melt 1 tsp. of butter, add the minced garlic and fry until fragrant but not browned. Add the shrimps and cook 2-3 minutes or until done.
In a small bowl smash the avocado, then add in the cream cheese, salt and black pepper. Mix well.
Spread about 1 tsp. of the avocado mixture onto each slice, add 1 shrimp (placed off-centered) and start rolling it up to form a pinwheel. You can use a toothpick to secure.You will get approximately 16 cucumber rolls.
Serve with lemon slices.
Notes
Don't prepare the filling in advance and don't assemble the rolls. Cucumbers throw lots of moisture that can make them too soggy. EQUIPMENT A mandoline slicer.
