Chop most of the strawberries, reserving some for garnish. Blend the cottage cheese until smooth in a food processor. Stir in the gelatin powder and drained crushed pineapple until evenly mixed.
Gently fold in the whipped topping and the chopped strawberries until just combined.
Transfer the mixture to a serving bowl, cover it, and refrigerate for a minimum of 2 hours until it sets. Garnish with the remaining strawberries, either leaving them whole or slicing them.
