Make the Sunflower dill spread: In a blender, combine the sunflower seeds, water, garlic, lemon juice, rice vinegar, salt, and a generous pinch of pepper. Blend until smooth. Add the dill and blend until just combined. You want the dill flecks to incorporate, but you don’t want the puree to turn green. Chill until ready to use. Stir before using.

Assemble the sandwiches with a thin layer of the sunflower spread, followed by overlapping rows of the sliced cucumber, turnip and radishes (see photo). Gently press the vegetables down onto the bread to ensure that they will hold together. Use a sharp chef’s knife to slice off the crusts and then slice the sandwiches in half into rectangles. Garnish with chives and/or microgreens.
