Rinse the cherry tomatoes and halve them. Rinse the half cucumber and cut it into small, uniform pieces. Place the prepared vegetables on a cutting board.
Heat a dry skillet over medium heat. Toast the mixed sunflower and pumpkin seeds briefly in the hot skillet until they begin to puff and turn light brown. Remove the seeds immediately from the pan and let them cool completely on a plate.
Take two bowls and divide the cottage cheese equally over the bottom as a base layer. Place the halved cherry tomatoes and cucumber pieces on top of the cheese. Drizzle the olive oil in a thin stream over the top.
Sprinkle the cooled toasted seeds over the bowl contents. Tear the fresh basil leaves into rough pieces, distribute these last over the two portions, and serve the bowls immediately.
