Cook the ground beef along with the onion, bell pepper, and minced garlic in a soup pot or Dutch oven over medium-high heat until browned, breaking up clumps as you go.
Drain the beef and return it to the pot.
I left my chopped bell pepper slightly larger because I prefer it to have a bit of a bite in the finished soup. Prefer yours softer? Simply dice it smaller so that it cooks through more quickly!
