Scrambled Egg and Sausage Tacos with Avocado and Scallion Recipe

Heat vegetable oil in a large nonstick skillet over medium high heat. When shimmering, add sausage and red onion and cook, breaking up with a wooden spoon, until sausage is cooked through and onions are soft, about 5 minutes. Remove from pan with a slotted spoon and reserve. Wipe out skillet with a paper towel. In a bowl combine avocado and lime juice. Season to taste with salt and pepper. In cleaned skillet heat butter over medium low heat until butter has melted, then add beaten eggs and cook, stirring frequently, until just beginning to hold together and custard like. Fold in reserved sausage and onions and remove from heat. Season to taste with salt and pepper and immediately transfer to a bowl. Divide scrambled eggs evenly between tortillas, top with avocado and scallions and serve immediately passing chopped cilantro, sliced lime and hot sauce if desired.
