Super easy to make for a large crowd.

Place 3-5 lbs of boneless Chicken breasts in Insta-Pot

Add 1 cup canned chicken broth or 1 cup of water and either one bouillon cube or 1 cup water and one tablespoon "Better than Bouillon" Chicken base (this is what I use).

Manual Cook high 18 minutes, fast steam removal and shred.  Pour favorite BBQ sauce over it and mix well.

If making this for a crowd, repeat recipe for a second batch and then place all shredded chicken in a Crock-pot to keep warm.
