Preheat the oven to 375 degrees F.
In a medium bowl, beat the eggs, Romano, milk, 1/2 teaspoon salt and 1 pepper with a whisk. In a 12-inch nonstick skillet with an oven-safe handle, melt the butter on medium-high heat. Stir in the asparagus and the remaining 1/4 teaspoon salt, and cook 4 minutes. Add the green onions, and cook 2 minutes, stirring often. Spread the vegetable mixture evenly in the skillet.
Reduce the heat to medium-low. Pour the egg mixture into the skillet and cook without stirring until the mixture starts to set around the edge, 4 to 5 minutes. Place the skillet in the oven and bake until set, about 10 minutes. Invert the frittata onto a serving plate and cut into wedges.
