Wash the cucumber, cut in half lengthwise. Remove the seeds with a spoon and cut into 8 diagonal pieces (2-3 cm wide). Mix cottage cheese and Roquefort, season with salt and pepper and fill 1-2 tablespoons into each cucumber piece.
Sprinkle with coloured pepper and cress. Wash the cherry tomatoes. Cut 2 pieces into quarters and put them on the cucumber morsels. Halve the remaining tomatoes. Arrange 2 halves with 2 cucumber morsels on plates.
