1 tablespoon vegetable oil
1 pound lean ground beef
1 small onion, chopped
1/2 cup sliced green onions
6 cloves garlic, minced
1 tablespoon Worcestershire sauce
1 teaspoon salt
2 tablespoons chili powder
1 teaspoon ground black pepper
8 hamburger buns
1 large tomato, seeded and chopped
3 tablespoons lemon juice
1 tablespoon vegetable oil
Preheat oven to 450 degrees F (230 degrees C).
In a large bowl, mix together oil, ground beef, onion, green onions, garlic, Worcestershire sauce, salt, chili powder, black pepper and hamburger buns. Roll into 1 inch rectangles; place on sheet pan.
Heat oven to 400 degrees F (200 degrees C).
Bake in preheated oven until well browned, about 15 minutes. Reduce heat to 350 degrees F (175 degrees C).
Heat 350 degrees F (175 degrees C) oil in a large skillet over medium-high heat. Add tomato mixture; cook, stirring, for 5 minutes or until tomatoes are tender and meat juices run clear.
Using a large spoon, dip buns in tomato sauce. Place in oven to rest overnight. Spoon tomato mixture into hamburger buns. Repeat with remaining veggie mixture and tomato sauce. Cover and refrigerate overnight.
When within 10 minutes of removing from pan, remove buns and place in refrigerator. Flip buns and allow to cool completely. While unbaking buns, brush tomato sauce over all.
While buns are baking, rinse and drain tomatoes and cheese. Melt margarine in small saucepan and stir 2 tablespoons tomato mixture over chicken; add tomato sauce and tomato mixture.
Bake up to 45 minute in the preheated oven. Meat tenders should be cooked through but white meat should have a nice golden color.
