I’ve done the Carroll Shelby mix before. I usually use Wick Fowler’s 2 Alarm Chili Spice mix. The spice mix is just one variable.
1 lb ground beef, browned
1 lb ground sausage, browned
1 lb frozen fajita vegetable mix
1 15 oz can each of black beans, dark red kidney beans, and light red kidney beans, all drained
1 15 oz can diced tomatoes
1 small can Rotel diced tomatoes and jalapeños
1 bottle of tomato juice
Get it all in the crock pot by 11am and dinner is set.
That’s what I do. I suspect chili is a lot like religion and politics for most people. They like what they like and it’s hard to sway people from their preference.
