In crockpot whisk together broth, garlic, soy sauce, brown sugar, and sesame oil.

Add stew meat, cook on low for 4-6 hours. (6-8 if, like me, you're putting the meat in frozen)

Mix corn starch with 1 c cold water. Stir mixture into beef.

Add frozen broccoli on top. Cook another 30 minutes.

Serve over prepared white rice. (Or lo mein noodles)
