Beef Satay Wraps

Please someone tell me I'm not the only one who frequents PF Changs simply for their lettuce wraps? I eat just that when we go. Its deliciousity- and I refuse to share.
While this is not the exact same thing- it's good, and pretty easy to make!

1/2 c. beef broth
(make sure it's just 1/2 c. and not the whole can- I have made this mistake before)
1/3 c. smooth peanut butter
2 tsp. cornstarch
1 tbl. vegetable oil
1 tbl. ground ginger
3 minced garlic cloves
1 lb. ground beef
1 c. shredded carrots (they sell them pre-shredded in bags by the bagged salad!)
1/4 c. thinly sliced green onion
2 tbl. soy sauce

Boston Lettuce leaves
Chopped peanuts

In a jar with a lid (maybe even the pb jar- if it's near empty?) combine broth, peanut butter, and cornstarch. Shake well to blend- shake that baby hard! Set aside.

In skillet, heat veggie oil over medium high heat. Add ginger and garlic. Cook for 30 sec. and then add beef. Brown for 5 minutes. Shake sauce again and pour into skillet- cook for 2-3 mins. Remove from heat and stir in carrots, green onion, and soy sauce. Serve wrapped in lettuce with peanuts.
