Sweet and Sour Pork

Great recipe!  Delicious and fairly healthy.

3/4 lb pork tenderloin (cut into bite-sized pieces)
1 1/2 T balsamic vinegar
1/4 t plus salt
1 t soy sauce
1/2 t cornstarch
1 1/2 T ketchup
2 T sugar (splenda works well too)
1/6 c water
2 T sesame oil
1 1.2 cloves garlic, minced
1-2 scallions, roughly chopped

Toss pork with 1/2 T vinegar and a pinch of salt.  Let sit for 15-30 mins.  Mix the rest of the vinegar, soy sauce, cornstarch, ketchup and sugar, water and 1/4 t salt.  Mix and let sit until pork is done.  Heat 1 T sesame oil in a wok on high heat.  Add pork, turning to brown on all sides, about 1-2 mins.  Remove pork (even though it's not cooked through yet).  Rinse out wok, then return to heat.  Add another drizzle of oil, then the scallions.  Saute for 1-2 mins.  Add pork and the sauce.  Cook until pork is cooked through and sauce is thickened.  Serve warm.

Note: If you want, you can add veggies to this and make it a stir-fry as well.  Add 2 carrots (thinly sliced) 1/4 green pepper (chopped), 1/2 c mushrooms (chopped) and/or 1 cup snow peas (halved) or whatever other veggies you like.  Add "harder" veggies with the scallions.  Add "softer" veggies with the pork.
