In a bowl, place the crumbled cottage cheese, cream cheese, grated cheese, and sriracha. Season with salt and pepper to taste. Blend until smooth.

In another bowl, lay out a piece of cling film. Transfer the mixture onto it.

Wrap and tie with the string to shape it into a "pumpkin." Place in the refrigerator for a few hours.

Then pour the chips into a bag and crush them finely. Pour out onto a cutting board.

Gently remove the creamy pumpkin from the cling film and roll it in the crushed chips.

Transfer to a plate and decorate with a pepper stem.
