Cut the cucumber lengthwise with a vegetable cutter into thin strips.
In a small bowl, mix the cooked shredded chicken with cream cheese and spicy sauce. You can add some mayonnaise sauce and a bit of salt and pepper.
Lay a strip of cucumber on a flat surface. On one end, place a generous spoonful of the mixture and two or three avocado cubes. Roll carefully, not to over tighten so that the filling does not come out.
Repeat this procedure with all the cucumber strips. You can sprinkle some sesame seeds on top when serving.
*You can use nori sheets instead of cucumber. You can add cauliflower rice in the place of regular sushi rice.
