Preheat oven to 375*, Clean bell pepper and peel onion, then cut in large chunks and mince in a food processor. Put a wire rack on a baking sheet and set aside.
In a large bowl combine ground beef, sausage, minced onion and bell pepper, breadcrumbs, Worcestershire sauce, garlic powder, salt, black pepper, and beaten egg. Mix well with hands.
Shape into oval steaks and put on wire rack. Bake for 25 minutes.
Spray a 9x13in. baking dish with nonstick spray. Arrange steaks then make gravy.
Using a medium pot, pour in beef broth, reserving 1/2 cup to make a slurry and set aside. To the pot add onion and garlic powder, 1 tsp. Worcestershire sauce and brown gravy packet. Stir with a whisk making sure there are no lumps. Turn heat on and bring to a boil.
In a small bowl put the reserved 1/2 cup of beef broth and then, using a fork or small whisk, mix in the cornstarch. This is your cornstarch slurry.
While broth is boiling, pour in the cornstarch slurry, making sure to stir with a whisk as you pour.
Let boil for a minute to thicken a little then pour over steaks. Reduce oven temperature to 350 *. Bake steaks for 30 minutes.
