Place roast in the slow cooker, and cover with taco seasoning.
Pour one cup of salsa Verde over top. Add one can of corn (with the juice) and 1/2 cup beef broth.
Cook on high for 3-4 hours, or low for 6-8. When it is finished cooking, pull from the slow cooker and shred, placing it back in the slow cooker when finished.
Mix the shredded beef with the corn and liquid.
Serve with favorite taco toppings: cheese, sour cream, tomatoes, and lettuce.
Notes
To turn this into a freezer meal:Add roast, taco seasoning, salsa, corn and beef broth into a gallon-sized freezer bag. Squeeze out as much air as possible and seal bag closed. Place freezer bag into freezer and it will last 60-90 days. When ready to use, spray inside of slow cooker with non-stick cooking spray and dump ingredients from bag into slow cooker. Place the lid on top and cook for 9-10 hours on low heat (you can cook it for 5-6 hours on high heat, but it will not be as tender as cooking it low and slow. We highly recommend low and slow!). Follow the rest of the instructions as written.
