Cook the tater tots according to the package directions
Heat oven to 400 degrees.
Lightly oil a deep pie dish or rockcrok. (That's what I used.)
Gently lay the tater tots into the dish.
Sprinkle on the cheese and bacon.
Bake for 5-8 minutes to melt the cheese.
For the spicy mayo, whisk the mayo, sour cream and Sriracha.
Drizzle over the casserole and sprinkle with chives.
