Got this recipe from the on-staff nutritionist of an upscale grocery store where I live. I've tried many beef/broccoli and beef/peppers recipes and this one was a hands down hit with my 7, 12 and 16 yr-olds, not to mention my DH. There are no onions or mushrooms in this recipe for my kids to pick out, yet it was very tasty. You can add all sorts of alternative ingredients, (like onions and mushrooms, but it doesn't need it). I make the marinade, do all the chopping and cook the broccoli early in the day so I can quickly cook it at night. Prep Hint: a semi-frozen steak is much easier to slice. Garlic, Ginger, Peppers, Broccoli amounts can all be adjusted to your taste.
