I love french onion soup, my DH&DS's love meat, so this is a recipe we all enjoy. This is an open-sandwich. Better Homes and gardens recipe.
I double the sauce so the toasted bread will be saturated
In a large skillet, melt butter or oleo. Add steaks and cook over medium high heat for 2-3 minutes on each side or till done. Remove from skillet, reserving the drippings. Cook the onion in the drippings until tender. Combine the broth, cornstarch, Worcestershire sauce, garlic powder, and a dash of pepper. Add to skillet. Cook until bubbly. Cook and stir 2 minutes more. Place on toasted bread top with swiss and onion mixture.
