I wasn't able to find all the ingredients at our no frills type grocery store. I'm going have to plan ever further ahead to try new recipes so I have the chance to go to a store with a wider selection.
The items with strike through I didn't have or didn't use.
1/4 cup low-sodium soy sauce
3 tablespoons canola oil
2 tablespoons hoisin sauce
2 teaspoons sriracha
1 teaspoon salt
2 chicken breasts
1/4 cup scallions, minced
I put it in a ziplock bag with 5 breasts in the fridge for a couple hours. When on the grill it turned out like this:
My wife liked it and so did my toddler (though it was heavily dipped in BBQ sauce). I'm certainly going to make this again. Next time I will get the sesame oil or use sesame seeds, score the breasts before putting them in the bag, and of course let it marinade for longer (like overnight).
