Finely mince the cucumber, carrot, and red bell pepper.

In a large bowl, mix together all the minced vegetables.

Roughly chop the peeled and deveined shrimp.

In a skillet, saute the chopped shrimp in olive oil until just about pink.

Let the shrimp cool slightly.

Add the sauteed shrimp to the minced vegetables.

Season the mixture with salt.

Take a wonton wrapper and place a small amount of the filling in the center.

Wet your index finger and trace it around the edge of the wonton wrapper.

Pinch each edge of the wonton to make a triangle.

Bring each of the three tips up together to create a bundle and seal.

Repeat the filling and folding process until all the filling is used.

Prepare your steamer with water and heat it for a minute or so.

Lay lettuce leaves on the bottom of the steamer to prevent sticking.

Steam the dumplings in batches for about 2-3 minutes, or until the wontons become translucent.

Serve hot with soy sauce or sweet and sour sauce for dipping.
