Kikkoman Sweet and Sour Sauce (for basting or simmering, not their dipping sauce, I get a 4lb 11oz bottle from Cash and Carry and I can get 4+ meals for my family of 7 out of one container. It's also much cheaper than the itty bitty store bottles.)
3 chicken breasts sliced very thin
1 red pepper, sliced thin
1 yellow onion, sliced
1 seedless cucumber cut into spears
1 large can pineapple chunks, drained or fresh pineapple
Pour some oil in a large skillet and stir fry onions and peppers. Add chicken, season with salt and pepper and cook until chicken is no longer pink. Add as much sauce as you like along with the cucumbers and pineapple and simmer for a few minutes then serve over rice.
Just a heads up that the cucumbers make this. Seriously my husband was totally skeptical and not a huge cucumber fan but the crunch they give is awesome. The other thing we love about it is having the chicken sliced really thin.
This recipe feeds my family of 7 with a little left over. So you may want to adjust if you don't feed an army every night. :)
