Begin browning ground beef in a large soup/stock pot or Dutch oven over medium high heat. When its halfway browned, add mushrooms, onion and bell pepper (reserve a little for garnish if desired); continue cooking until all ground beef is browned and drain if desired.

Add remaining ingredients to pot, bring to a soft boil, reduce heat to low, cover and simmer for 30 minutes to one hour (depending on the time you have)

Garnish with reserved raw veggies of desired. If you do dairy, you can also garnish with cheese.
