Place the sliced cucumber in a bowl with a good pinch of salt, toss lightly, and let it rest for about 10 minutes while you prepare the cream cheese mixture.
Stir the chopped herbs and garlic into the vegan cream cheese until fully combined.
Spread the cream cheese mixture on both slices of bread for each sandwich.
Remove the cucumbers from the bowl and pat them dry with a clean cloth.
Layer the cucumber slices in overlapping rows on the bread, then cut each sandwich into triangles.
Garnish with borage flowers (they taste like cucumber) and nasturtium leaves and flowers for the prettiest finishing touch.
