Set the pressure cooker to high for 0 minutes (yes, really)
do a quick release.
Add the cheddar cheese and bacon crumbles to the shredded chicken and mix the ingredients together.
Place the lid back on the pressure cooker (but don’t turn it on, it will be hot enough to melt the cheese and warm the bacon) for about 5 minutes. Letting the ingredients sit for a few minutes will allow the sauce to thicken.
