Ingredients

• Organic White Quinoa: To provide the bowl with a nutty flavor, along with protein & fiber. You can use any color that you have on hand—white, red, or multi-color.
• Organic Cauliflower Florets: Fresh or frozen!
• Organic Yellow Baby Potatoes: These small potatoes, often referred to as new potatoes, are the perfect addition to add some heartiness.
• Organic Spicy Honey Mustard: A yummy combination of raw tahini, honey, Dijon mustard, fresh lemon juice, chipotle chili powder, cayenne pepper, sea salt, & black pepper.
• Organic Avocado: It’s the perfect creamy topping to mellow out the spicy honey mustard!
• Organic Fresh Herbs: Cilantro, dill, basil, or whatever you have on hand!
• Organic Greens: Any greens work great. Baby spinach, arugula, chard, and/or massaged kale.
• Organic Avocado Oil: This is my favorite oil to use while baking because it can withstand high temperatures.

How to Make

1. Quinoa. Prepare quinoa as instructed on the package.
2. Roasted Vegetables. Preheat the oven to 425 degrees F & line a sheet pan with parchment paper. On one side, toss the cauliflower florets with the seasonings & avocado oil. On the other side, toss the potatoes with the seasonings & avocado oil. Bake for 20–25 minutes, flipping halfway.
3. Spicy Honey Mustard. In a mixing bowl, add the ingredients & whisk to combine. Add the water a little at a time until a semi-thick, pourable concoction is achieved. Set aside.
4. Serve. Divide the fresh greens, quinoa, roasted vegetables, avocado, & fresh herbs between bowls. Pair with the spicy honey mustard & enjoy!

Tips for Making this Plant-Based Bowl Recipe Perfectly

• Organic Quinoa: You can use any color that you have on hand—white, red, or multi-color.
• Organic Raw Tahini: If you don’t have it, you can replace it with organic raw cashew butter.
• Organic Honey: Manuka honey, local raw unfiltered honey, or organic pure maple syrup to make it vegan will all work.

Storing & Reheating

This Roasted Cauliflower & Baby Potato Quinoa Bowl with Spicy Honey Mustard is the perfect plant-based recipe for healthy leftovers & meal prep! 

Storage. Transfer ingredients to separate airtight glass containers. I don’t recommend slicing the avocado until the bowl is ready to be enjoyed.

Reheating. To reheat, preheat the oven to 350 degrees F. Transfer the roasted vegetables & cooked quinoa to an oven-safe bowl. Place in the oven for 10–15 minutes, until warmed through. To serve, pair with the remaining bowl ingredients.
