Melt butter in a large nonstick skillet over medium heat. Add green onions and cilantro, and saute 1 minute. Add eggs, salt, pepper, and cook, without stirring, until eggs begin to set on bottom. Draw a spatula across bottom of pan to form large curds. Continue to cook until eggs are thickened but still moist; do not stir constantly. Remove from heat, and gently fold in 1 1/2 cups Cheese Sauce and sausage.
