Thanks to other reviews, I was able to make this close to a 4-5 star recipe but am still rating it a 2 because I changed it quite a bit. I added about a tablespoon of hoisin sauce and a teaspoon of chili garlic sauce to the steak marinade and let it sit for about half an hour soaking all that up. Then with the onion/pepper mixture I added some ginger and red pepper flakes all in an attempt to spice things up. It worked! I also served with udon noodles instead of rice. In the end it was very tasty.
I agree with the prior reviewer who said it was just okay. I'd need to add more seasonings - maybe something with a little kick to it? - if I made it again.
