Notes

  • Quinoa medley: I love to use a quinoa medley that includes rice and other grains for this recipe, as I find it's hearty but not too heavy. My blend includes quinoa, brown long rice, millet, amaranth, and split red lentils. You can also use all quinoa, rice, lentils, or any other grain. Or you could also make your own blend, just be sure to pay attention to the cooking times of each to make sure they're roughly the same.
  • The spices: In place of the spices, you can substitute 2 teaspoons of taco seasoning.
  • Meal Prep: You can: 1) Make the filling ahead of time and refrigerate until you're ready to fill and cook the peppers or 2) Make the filling and fill the peppers, and refrigerate them until you're ready to pop them in the oven. Add a few minutes to the baking time if they've been refrigerated.
  • Reheating: Leftovers can be reheated 1) one or two at a time in the microwave. I find a couple of minutes on high power works well. Or 2) reheat the whole dish in the oven. Heat oven to 400 F, cover the baking dish with foil, and heat for around 45 minutes, with the last 10 minutes uncovered. 
  • Freezing: Fill the peppers (don't top with cheese), and pop them into a in a freezer bag, press out as much air as you can, and freeze for up to 3 months. Bake the peppers from frozen, covered, in a 400 degree oven for about 1 hour. Sprinkle the cheese on top and bake for an additional 15 minutes.
