The seasonings are roughly:

-salt and pepper (1/2 tsp each)
-rooster sauce (Worcestershire) (1 tbsp)
-onion powder (1/2 tsp)
-garlic powder (1/2 tsp)
-cumin (1/2 tsp)
-tomato paste (1 tbsp)
-1 bay leaf
-cornstarch (1 tbsp as a thickener)

You can also use beef broth or stock instead of water for a beefier flavour.

A few shots of Frank's hot sauce is always an addition welcomes by my crew.

I also sometimes put a carrot through the micro grater and add it for a little extra flavour that's too small for us carrot haters to see.
