1 (8 oz.) can no-salt added tomato sauce
1/2 c. ketchup
1 1/2 tbsp. Worcestershire sauce
1 tsp. prepared yellow mustard
1/2 tsp. dry mustard
1 tsp. molasses
1 clove garlic, finely minced
1/4 tsp. freshly grated orange peel
Pinch ground cloves
Hot pepper sauce to taste
1 lb. very lean ground sirloin
1/2 sm. onion, finely chopped
6 whole wheat hamburger buns, toast if desired

In a saucepan over low heat, combine first ten ingredients. Mix well and simmer while preparing meat.

Next, heat a heavy, non-stick skillet at least 10 inches in diameter, over medium high heat. Add ground beef and saute, stirring occasionally, 4 to 5 minutes, or until meat is no longer pink. Pour contents of pan into a strainer or colander lined with paper towels. Allow fat to drain out.

Add onion to pan and saute, stirring frequently, about 5 minutes, or until translucent. Return meat to pan and add sauce. Heat 3 minutes, stirring occasionally. Add additional hot pepper sauce, if desired. Spoon 1/2 cup mixture over each bun. Serve immediately. The sauce and meat mixture freeze well.
