These quinoa stuffed peppers are practically a staple in our house. It's an easy meal to prepare ahead of time and cook later. You can even freeze them. When I make them, I like to make extras to freeze for lunches that week.
A few years ago, I got the idea from one of my favorite health & food blogs, Simply Nutritious by Kate (formerly A Healthy Passion). That recipe is no longer featured on her site but I posted about the first time I tried the recipe back in 2011 here.
I don't follow a recipe anymore and instead make the "stuffing" out of whatever we have on hand. It always includes quinoa and black beans and usually tomatoes, corn, cilantro and cheese.
I use a paring knife to hollow out the peppers and then stuff with the quinoa/veggie/cheese mixture. After arranging them on the baking sheet, I bake them at 375 for about 25 minutes. As you can see, sometimes I do one or two with no cheese.
After baking about 20 minutes, I add more cheese on top and bake a few more minutes. I like for both the cheese and the top of the green pepper to get nice and browned.
They are delicious served with salsa and sour cream. One of our go-to meals for sure!
I hope this gave you a good idea, enjoy!
