• 1 (15-oz.) can diced tomatoes, with juice
• 1 c. low-sodium beef broth
Generously spray the inside of the slow cooker with vegetable oil spray.
In a large skillet over medium heat, sauté the beef until it loses its raw color. Add onion and sauté briefly, until softened. Mix in garlic, oregano (or marjoram), cumin, chili powder, salt and jalapeños and sauté another minute or 2, until the mixture is fragrant. Scrape the mixture into the prepared slow cooker. Return the skillet to the cooktop. Pour in vegetable oil and warm it over medium heat. Stir in red bell peppers and green bell peppers and cook until tender, 7 to 10 minutes. Scrape bell pepper mixture into the slow cooker.
Pour the tomatoes and beef broth into the slow cooker. Cover it. Cook the chili on the low heat setting for 6 to 7 hours, until the beef is extremely tender and the vegetables have melded together.
