Slow Cooker Vegetable Quinoa Medle

Are you running out of easy, quick-to-prep healthy meals for weekdays? Let the slow cooker step in and take care of that for you with this Vegetable Quinoa Medley recipe. This dish is rich in fiber, nutrients, and flavor, plus it’s gluten-free and can be easily made vegan. It yields four generous servings, so there’s plenty left over to last you the week.

For this Vegetable Quinoa Medley, all that’s required of you is some light vegetable and herb chopping, whisking together a 4-ingredient tangy dijon dressing, and letting the slow cooker get to work for 3-4 hours on high while you watch Netflix, listen to a podcast, fold laundry—or all the above.

Five minutes before it’s finished, you’ll give the broccoli a quick steam so you can mix it in at the end. This way it doesn’t overcook or get soggy.

Slow Cooker Vegetable Quinoa Medley Cooking Steps

Honestly, I don’t associate vegetables and quinoa with much excitement or flavor. Without the right dressing or sauces, you have a bland and unmotivating dish on your hands. That’s why I’ve ensured this recipe is packed with a variety of textures and savory, fresh flavors so you’ll look forward to every bite and (hopefully) want to make it over and over again.

There’s also a nice array of vegetables in this recipe (let’s hear it for those immune-boosting phytonutrients!), including red onion, bell pepper, carrots, corn, peas, broccoli, and green beans. I’ve recommended using frozen vegetables to save time, but you can swap them out for whatever you happen to have in your produce drawer.

The same goes for herbs. I highly recommend using the suggested herbs in this recipe for added texture, freshness, and flavor. But if you’re not a fan of cilantro, basil, or green onion, you can use any other herb combination your heart desires. Italian parsley and dill would make good substitutes. Now, let’s get to it!
