Heat oven to top broil.
Cut a small section out of the top of each poblano pepper and scoop out the seeds and membranes with a teaspoon. (A grapefruit spoon with serrated edges works perfectly here if you have one.)
Prepare a baking sheet by covering it with aluminum foil. Place peppers with cut sides down on baking sheet and drizzle with olive oil or spray with cooking spray.
Broil peppers for about 5-7 minutes on each side, until skin is blistered but not completely blackened. Watch them carefully as they will burn quickly.
While peppers are cooking, in medium bowl, mix together the cooked quinoa, diced onion, bell pepper, garlic, cilantro, Snake Bite Datil Pepper Hot Sauce and Datil Zest. Remove peppers from oven and let rest for a few minutes before stuffing.
Reduce oven temperature to 400 degrees Fahrenheit.
Divide stuffing evenly between the peppers and return peppers to the oven for 20 minutes to thoroughly heat the stuffing.
Top peppers with shaved parmesan or vegan cheese if desired and return to the oven for another 5 minutes or until the cheese is melted and bubbly. Remove from oven.
Serve with more Snake Bite Datil Pepper Hot Sauce on the side or your favorite salsa.
