Combine the goat cheese, cream cheese, sour cream and parmesan. Process in the bowl of a food processor or mix with a spatula or wooden spoon in a medium bowl until mixture is combined.
Stuff the tomatoes
Slice tomatoes in half, widthwise. Using the small end of a melon baller or a small measuring spoon (like a ¼ teaspoon), carefully scoop out the seeds and core from each tomato. Arrange the tomatoes cut side up on a cutting board.
Using a small spoon, place about one teaspoon. of the goat cheese filling in each tomato, mounding it slightly.
Transfer the filled tomatoes to a platter, sprinkle with the chives and serve. Makes about 40 stuffed cherry tomatoes.
