Salted Pretzel Bites with White Cheddar Sauce

Spray tops of pretzel bites with water, then sprinkle with salt. (If desired, preheat oven to 350 degrees. Bake salted pretzel bites until warmed, 3 minutes.) Heat cream sauce base in a small pot over medium-low heat. Bring to a low simmer and cook, whisking, until sauce begins to thicken, 1 minute. Reduce heat to low; slowly add in cheese, whisking constantly. Cook until cheese melts and sauce has thickened; season with salt and pepper to taste. Serve pretzel bites with cheese sauce on the side for dipping.
