Broccoli Beef in the Crock Pot

I made this for book club and it turned out pretty good! It was super easy!

1-1.5 lbs steak (flank or skirt steak is best, I just used what I had on hand)
1 C Beef Broth
2/3 C Soy Sauce
1/3 C Brown Sugar
1 Tbsp. Oil
4 C Broccoli
Optional: Red Pepper Flakes
2 Tbsp. Cornstarch
4 Tbsp. Beef Broth

Cut steak into very thin pieces. Put steak, 1 C beef broth, soy sauce, brown sugar, oil, garlic, and red pepper flakes (optional) in the crock pot. Cover and cook on high for 2-3 hours or low for 4-5 hours.

15-20 minutes before serving, uncover crock pot. In a small bowl whisk together corn starch and 4 Tbsp. Beef Broth. Add it to the crock pot. Chop up broccoli pieces to your desire. Add them to the crock pot as well. Stir together the ingredients. Let finish cooking for 15-20 minutes. Broccoli should be soft and then it is ready to eat. Serve over rice.
