In a small mixing bowl, combine softened cream cheese, Greek yogurt, finely chopped chives, and fresh dill. Add a pinch of ground pepper to taste. Mix everything together until smooth and creamy, about 2-3 minutes.

Preheat your toaster or skillet over medium heat. Toast slices of whole wheat bread until golden-brown, about 3-5 minutes.

Slice the ripe tomatoes into ¼-inch rounds.

Spread the herby cream cheese mixture on one side of each toasted slice. Layer sliced tomatoes on one slice and top with the other slice, spread side down.

Cut the sandwich diagonally and serve. Optionally sprinkle flaky sea salt or herbs on top.
