Shred the cooked chicken and finely dice the red onion. Soak the onion in water for 10 minutes to mellow its flavor, then drain.

In a large bowl, combine shredded chicken, soaked onion, chopped cilantro, and cubed avocado. Stir gently to mix.

Blend cottage cheese, mayonnaise, onion powder, lime juice, cilantro, salt, and pepper in a food processor until smooth.

Pour the smooth dressing over the chicken mixture and stir until everything is evenly coated.

Thinly slice the English cucumbers and pat them dry. Arrange cucumber slices overlapping on parchment paper.

Spread whipped cream cheese over the cucumber slices to help hold the roll ups together.

At the lower end of each cucumber slice, place a generous amount of chicken salad mixture and roll tightly.

Slice the roll ups into bite-sized pieces and garnish with everything bagel seasoning and hot sauce if desired.
