Cut chicken breasts into large pieces, and season with garlic powder, onion powder and salt and pepper
Set the instant pot to “saute”, add the olive oil and allow to heat.
Cook the chicken until golden, working in batches if necessary.
Mix together the chicken stock, buffalo sauce and melted butter.
Pour mixture over the chicken, put the lid on the instant pot and cook on high pressure for 5 minutes. Allow the pressure to release for 10 minutes (Natural Pressure Release, or NPR), then perform a quick
release.
Open the lid and shred the chicken.
Separate the buns – tops from bottoms. Top the bottom buns with the chicken mixture, a little ranch, and blue cheese crumbles. Add the top buns, and serve!
