Place your roast in an Instant Pot and pour Coca Cola over roast. Sprinkle brown sugar over roast, followed by the taco sauce.
Put on the lid and push the meat button. Cook on high pressure for 90 minutes. Then do a quick release.
When it is finished cooking, take the pork roast out of the Instant Pot and shred. Then add back into the juices in the Instant Pot.
Using a slotted spoon, serve on tortillas with your favorite toppings. I like black beans, onions, tomatoes, guacamole, and cheese. You could also serve it on lettuce and make a delicious salad.
Notes
Place roast, Coca Cola, brown sugar, and taco sauce into a gallon-sized freezer bag. Place freezer bag into freezer and it will last up to 90 days. When ready to use, dump ingredients from bag into Instant Pot and add 1/2 cup chicken broth or water in with the frozen food. Place the lid on top, move the valve to SEALING, and press the MANUAL button. Set timer for 180-240 minutes (or about 30 minutes per pound of your roast). Do a NATURAL RELEASE when the timer is done – I even like to let it sit in the Instant Pot for a few hours so that it falls apart so easily. Follow the rest of the instructions as written.
