Toss the stew beef with 2 Tbls tapioca starch (flour) and 1 tsp salt until the meat is coated evenly
Add the oil to your Instant Pot and turn to 'saute' mode. Let it heat up and then brown the meat in batches (2-3 minutes for each batch) then set the beef aside
Add in a little more oil if needed and add the diced onions, diced poblanos, diced jalapeno, and garlic to the Instant Pot. Let saute for 2-3 minutes while stirring and the turn the Instant Pot off
In a small bowl add the chopped chipotles in adobo*, 1 tsp of tapioca starch and the remaining spices. Mix it all together until it forms a paste
Add the beef to the veggies in the Instant Pot and the add in the spice mixture. Stir it to combine and then pour in the tomato sauce and beef broth and stir. Close the lid and move steam valve to seal. Set to manual/pressure mode and time for 25 minutes
Once the timer goes off, do a quick release of the steam. Serve with toppings of choice
Notes
*Can also use cubed beef chuck roast, but trim the excess fat first*If you can't find Whole30 compliant chipotles in adobo, combine 2 Tbls of tomato paste with a diced jalapeño instead *Make sure you use canned tomato sauce, not marinaraDisclaimer - this is spicy chili. We like it hot in our family :)
