Heat 1 tbsp olive oil in a large nonstick skillet. Add both bags of cauliflower gnocchi and saute until golden brown on each side, approx 10 minutes. ***DO NOT COOK ACCORDING TO PACKAGE! Adding water causes the gnocchi to become soggy.
While gnocchi is cooking, make your homemade buffalo sauce. In a medium pot combine the hot sauce, vinegar, Worcestershire sauce, and garlic powder. Add butter and whisk while it's melting. When butter is incorporated, stir in cornstarch dissolved in 1 tbsp water. Whisk until sauce thickens, about 30 seconds. Turn off heat.
Once gnocchi is cooked add shredded chicken and ½ cup of cheese. Carefully pour buffalo sauce over gnocchi and chicken, gently stirring to evenly coat.
Transfer to a baking dish and sprinkle more cheese on top.
Turn on broiler to high. Place casserole dish in the oven and broil for 2-3 minutes until cheese is melted and golden brown.
Remove from oven and add sliced green onions. Drizzle with ranch dressing and hot sauce for serving.
