Preheat oven to 400 degrees.
Combine the tomato sauce, barbecue sauce and
sugar in a small saucepan over medium heat. Heat the
mixture until it begins to bubble, stirring often,
then remove it from the heat.
In a large bowl, add all but 2 tablespoons of the
tomato sauce to the meat. Use a large wooden spoon
or your hands to work the sauce into the meat until
it is very well combined.
Combine the remaining ingredients with the ground
sirloin-- flour, salt, onion powder and ground
pepper. Use the wooden spoon or your hands to work
the spices and flour into the meat.
Load the meat into a loaf pan (preferably a meatloaf
pan with two sections which allows the fat to drain,
but if you don't have one of those a regular loaf
pan will work). Wrap foil over the pan and place it
into the oven for 30 minutes. After 30 minutes, take
the meatloaf from the oven, remove the foil and, if
you aren't using a meatloaf pan, drain the fat.
Using a knife, slice the meatloaf all the way
through into 8 slices while it is still in the pan.
This will help to cook the center of the meatloaf.
Pour the remaining 2 tablespoons of sauce over the
top of the meatloaf, in a stream down the center.
Don't spread the sauce. Place the meatloaf back into
the oven, uncovered, for 25-30 minutes or until it
is done. Remove and allow it to cool for a few
minutes before serving.
Serves 4.
