This Paleo slow cooker beef teriyaki was a HUGE hit in my house! With only 15 minutes of prep time, this low-carb, Whole 30 and Paleo-friendly dish makes a wonderfully healthy dinner recipe for those busy weeknights.
During the last hour of cooking add the bell peppers and onion. Continue cooking for the last hour on low.
Once beef is completely done and veggies are cooked to your desired crispness, sift the arrowroot starch into the Crock-Pot. Stir to completely combine.
Serve teriyaki beef over cauliflower rice and enjoy!
