Preheat oven to 375 degrees. Line a baking sheet with parchment and roast the tomatillo, jalapeño, and onion 15-20 minutes. Set aside and allow to cool.
Whirl the roasted veggies and all remaining tomatillo sour cream ingredients in the food processor.
Heat a Dutch oven or heavy bottom soup pot on the stove over medium high heat, add olive oil, and brown the hamburger and steak.
Add seasonings and dried chilis. Add diced veggies. Stir everything together, then add canned tomatoes and tomato paste. Add beef broth and salt and pepper
Lower the heat and simmer for an hour. The longer this cooks, the better it tastes, ready in as little as 30 minutes but perfect in 2 hours.
Serve with the tomatillo sour cream, radishes, cilantro, jalapeños, and chips. This makes a great chili dog. Enjoy!
