I love this dish, been making it for years. I use any kind of bagged stir-fry veggies, add extra broccoli and any other veggie I have on hand, either canned or fresh pineaple works great. I do cook the chicken first, remove it to cook the veggies, then stir the chicken back in. I also coat the chicken in corn starch first to thicken up the sauce. Put in the pineapple last, stir in enough Sriracha to make my eyes water, and top with peanuts. Everyone loves it!
