Preheat the oven and bake the tater tots according to the package directions—usually 425°F for 25–30 minutes.
Flip them halfway through for even browning. Once cooled slightly, slide 6 tater tots onto each wooden skewer. Line a baking sheet with a silicone mat or parchment paper and place the skewers on it.
Sprinkle shredded cheese over the tater tots, then add crumbled bacon pieces.
Return the skewers to the oven and bake for another 5 minutes, or until the cheese is melted and bubbly.
Remove from the oven and top with chives. Serve warm, drizzled with sour cream on top or on the side for dipping.
