It’s also easy to turn our bell pepper, mushroom, and onion medley into a main dish. Here are a couple of easy ideas:

  • Make a one-dish pasta dinner: Once cooked, toss the veggies together with pasta (rotini is a good choice) and crumbled Italian sausage, top with grated Parmesan, and serve.
  • Make a flatbread: Buy some naan (we love Stonefire roasted garlic flavor) or other ready-made flatbreads and top with the cooked veggies and a blend of shredded Italian cheeses.
  • Make a low-carb “rice” bowl: Serve the vegetable medley along with shredded rotisserie chicken over steamed riced cauliflower, and drizzle with balsamic glaze for some added flavor.

Sweet Pepper, Mushroom and Onion Medley

Yield: 4 servings
Prep Time: 10 minutes
Cook Time: 35 minutes
Total Time: 45 minutes

This easy side dish medley of sweet bell peppers, mushrooms, and onions is flavored with sautéed garlic and a splash of balsamic vinegar.

Ingredients

  • 3 large, sweet bell peppers (red, orange, and/or yellow)
  • 3 tablespoons olive oil
  • 1 medium onion, thinly sliced
  • 3 cloves garlic, minced
  • 8 ounces cremini mushrooms, sliced
  • Salt and freshly ground black pepper
  • 1-1/2 tablespoons balsamic vinegar
  • 2 tablespoons chopped fresh parsley

Instructions

  1. Remove the stem, core, and seeds from the peppers and slice them lengthwise into thin strips. Set aside.
  2. Heat the olive oil in a large pan over medium heat. Add the onion and cook, stirring frequently, until they are very soft and golden in color, 7 to 8 minutes.
  3. Add the garlic and cook for another minute.
  4. Add the mushrooms, season with salt and pepper, and continue cooking, stirring from time to time, until any moisture given off by the mushrooms has evaporated and they've turned a rich golden brown, 6 to 8 minutes.
  5. Add the peppers, season again with salt and pepper, and continue cooking, stirring frequently, until the peppers have softened, 6 minutes.
  6. Add the balsamic, cover the pan, and cook for an additional 6 to 8 minutes, stirring every minute or so.
  7. Remove the cover and cook for 2 to 3 minutes longer, stirring often. The peppers should be sweet and very tender. Taste and adjust the seasoning as needed.
  8. Transfer the mixture to a large bowl, sprinkle with parsley, and serve family-style.
