Pat chuck roast dry with a paper towel
Cut up beef into 6 large chunks and sprinkle with salt and pepper
Press saute on Instant Pot and add oil. Sear the beef until slightly brown on a couple of sides. Add sesame oil, garlic, grated ginger, oinion, 1/4 cup of the coconut aminos, and maple syrup
Hit cancel, seal the lid and set Instant Pot to Manual for 45 minutes.
Natural release (which can take about 20 min) is preffered but you can quick release
In a separate pot on the stove, take 1/2 cup of the juices from the meat and slowly whisk in the arrowroot starch until it forms a thicker roux (and all arrowroot is dissolved). Add this back into the instant pot and stir into the meat.
I serve on Siete tortillas with slaw, cilantro, a lime wedge, avocado, and sriracha mayo on top. All these toppings are totally optional.
Picky eating tip: If your kids have a hard time eating raw veggies, cook the cabbage, slaw, and/or carrots in with the meat. It will be softer to eat and more disguised in the tortilla :) Have them "dip" in some smashed avocado with lime juice.
