Buffalo Cauliflower Dip

Preheat oven to 375°F. Toss together cauliflower and olive oil in a 9-inch cast-iron skillet. Cover with a lid or aluminum foil, and cook over high to steam, about 5 minutes. Uncover and cook over medium-high, stirring occasionally, until cauliflower is fork-tender and caramelized in spots, about 10 minutes.

Stir in butter. Once melted, stir in hot sauce; cook, stirring often, until sauce has reduced by half, about 3 minutes. 

Remove from heat. Stir in cream cheese and sour cream until fully combined. Sprinkle Cheddar on top, and bake in preheated oven until bubbly and slightly browned, about 10 minutes. 

Sprinkle with blue cheese and scallions. Serve with celery sticks, carrot sticks, potato chips, tortilla chips, and baguette slices.
