Preheat oven 375 degrees F
Heat extra-virgin olive oil in small skillet over medium-high heat. Add the chorizo and saute until the brown and the fat is rendered. Stir in the mushrooms and cook until just tender, 6 to 7 minutes. Transfer to small casserole or baking dish, top with cheese and bake until bubbly. Remove from the oven, garnish with scallions and serve with chips for dipping.
