Brown ground beef with desired amount of seasonings (I use seasoned salt & pepper), celery, onion & green pepper.
After it's browned, drain.... Even lean ground beef has some fat that can be spooned off. Tilt pan and it will gravitate to one side for easy removal.
Sprinkle flour and stir in evenly for thickening...
Add ketchup, worcestershire sauce and sugar.
Stir to mix evenly. Add approx 1/4 cup or more water to get to desired consistency. Simmer 5 minutes. Can serve immediately or freezes well for future use too.
