Using the olive oil, brown the ground turkey in a skillet or in the Instant Pot.
In a medium bowl, mix the tomato sauce, ketchup, chili sauce, tomato paste, Worcestershire sauce, soy sauce, brown sugar, and Dijon mustard. Pour it into a medium sized resealable freezer bag and seal. Be sure to take out as much of the air as you can.
In another medium freezer bag, put the browned ground turkey, garlic, and onion. Seal the bag and staple to the bag with the sauce. Freeze.
On cooking day...
Take it out of the freezer to thaw. Set your Instant Pot to the sauté function. Add the contents of the bag with the cooked ground turkey, onion, and garlic. Cook until the garlic and onion are fragrant and translucent.
Add the water and the contents of the bag of sauce.
Close and lock the lid on the Instant Pot and make sure the vent is closed. Set the Instant Pot to 8 minutes. Once the 8 minutes is up, allow the pressure to release naturally for 10 minutes. Open the vent and release the remaining pressure.
Serve on a bun with your favourite sides and enjoy!
