Southwest Stuffed Bell Peppers with Black Beans and Quinoa (Vegan, Gluten-Free)

Sharon Palmer

Is there anything more festive than these cheery, plant-based bell peppers, stuffed with a hearty, zesty filling of black beans, quinoa, corn, and tomatoes, and topped with avocado slices and creamy vegan ranch dressing? These feisty Southwest Stuffed Bell Peppers are a meal in one—and one of my favorite dinners for easy weeknights or weekend dinner parties. You can use any type of vegetable suitable for stuffing for this recipe, too, such as round summer squash, acorn or butternut squashes, large tomatoes, and small eggplants.
