Salsa Verde Beef

I can't remember where I got this from but it looked good so I tried it.  :)  It turned out very tasty and I served it in tortillas with lettuce, tomatoes, black beans and Beano.  Yes, I needed to serve it with Beano for the protection of my life.  LOL

Salsa Verde Beef

1 Tbsp. olive oil
2-3 lbs. stewing beef cut into  1 1/2" chunks
1/2 cup chopped onion
2 Tbsp. taco seasoning
1 cup salsa verde

Heat oil in a large skillet.  Add beef chunks and brown on all sides to carmelize.  Remove to crockpot.  Add onion to drippings and saute until lightly browned.  Stir in taco seasoning and heat about one minute.  Add salsa and stir, scraping up any browned bits.  Transfer liquid to crockpot.  Stir to combine.  Cook on low 6-8 hours.  Shred meat and serve on tortillas with whatever fixings you want.
