1 pound ground beef

1/4 cup dry bread crumbs

2 Tablespoons milk

1 Tablespoon Worcestershire sauce

1 teaspoon salt divided

1/2 teaspoon pepper

1/2 teaspoon garlic powder

1/2 pound fresh mushrooms sliced

1 teaspoon dried basil

5 Tablespoons butter or margarine divided

2 Tablespoons all purpose flour

1/2 cup half and half

1/2 cup water

1/4 teaspoon hot pepper sauce

1/4 cup shredded cheddar cheese

2 Tablespoons green onion chopped

Combine beef, crumbs, milk, Worcestershire sauce, 1/2 teaspoon salt, pepper and garlic powder; mix well. Shape into 3 or 4 oval patties; cook on both sides until no longer pink. Cook the mushrooms and basil in 2 Tablespoon butter over medium high heat until tender. Increase heat to high; cook and stir until most of the liquid evaporates. Melt the remaining butter; stir in flour. Gradually blend in cream. Add 1/2 cup water, hot pepper sauce and remaining salt; cook and stir on low until thickened and bubbly. Cook and stir for 2 minutes more. Add enough remaining water to make a medium thin sauce. Add mushrooms; heat through. Serve over beef patties; top with cheese and onions.
