Place bread slices on two ungreased baking sheets. Bake at 400° for 6-8 minutes or until lightly browned.
Meanwhile, in a large skillet, cook sausage over medium heat until no longer pink; drain. Set aside. In a small bowl, whisk the eggs, onions, salt and pepper. In the same skillet, cook and stir egg mixture until set. Stir in sausage.
Spread salsa over each bread slice. Top with sausage mixture; sprinkle with cheese. Bake 1-2 minutes longer or until cheese is melted. Garnish with sour cream and cilantro. Yield: about 2-1/2 dozen.
