I did a pared down, lighter-on-the-calories version of this and it was spectacular. I used 1 tbsp of olive oil supplemented with olive oil cooking spray rather than the peanut and sesame oils. I left out the cornstarch and just cooked the pork in the olive oil. I didn't have broccoli, so I used a green pepper, a red pepper, and an onion, all sliced. Oh, and I had 1.5 pounds of pork tenderloin, so I used it all.
I left the sauce unchanged (except used splenda brown sugar blend instead of brown sugar); it is delicious as written. My husband loved it even though he doesn't normally like sweet foods, and our three male guests raved about it.
I served it with a basic fried rice (3 cups cooked white rice, 1 egg, 3 tablespoons each of soy sauce and rice vinegar, all fried up together with olive oil).
