Prepare the Creamy Spread: Combine softened cream cheese, Greek yogurt, chopped chives, dill, and ground pepper in a bowl until smooth and creamy.

Toast the Bread: Preheat your toaster or oven and lightly toast whole wheat bread until golden brown, about 3-5 minutes.

Slice the Tomatoes: Carefully slice ripe tomatoes into ¼-inch thick rounds.

Assemble the Sandwich: Spread herby cream cheese mixture on one side of each toasted bread slice, layer tomato slices, and top with the other slice.

Garnish & Serve: Optionally sprinkle flaky sea salt and cut sandwich diagonally for serving.
