SLOW COOKER (Active Time: 20 minutes, Total Time: 5 hours, 20 minutes)

1. Preheat large sauté pan on medium-high 2–3 minutes. Coat beef with 2 tablespoons seasoning mix packet (from chili kit). Pour oil in pan, then add beef (in batches, if needed); cook 1–2 minutes, turning occasionally, or until browned on all sides. Transfer beef to slow cooker. Add garlic, trinity mix, stock, diced tomatoes, tomato juice, and remaining seasoning mix packet; stir to combine. Cover with lid and cook on HIGH for 4–5 hours (or LOW for 7–8 hours) until beef is pull-apart tender (145°F).
2. Remove beef and shred with two forks, then return to chili.
3. Combine masa flour packet (from chili kit) and water, then stir into chili; re-cover and let stand 3–4 minutes or until chili thickens. Top with green onions; serve.

Note: For a spicier chili, add the red pepper packet (from chili kit) with all other ingredients into the multicooker/slow cooker.
