Roasted Veggie + Quinoa Meal Prep Bowls

By popular request: a simple, meatless meal-prep idea that’s nourishing, flavorful, and easy to make ahead. These bowls pair protein-rich quinoa with caramelized roasted vegetables and a tangy homemade tahini sauce. They store well, reheat beautifully, and make weekday lunches or dinners effortless.

Quinoa is naturally gluten-free and one of the few plant foods that provides all nine essential amino acids, making it an excellent base for vegetarian meals. It’s also a good source of fiber, magnesium, B vitamins, iron, potassium, calcium, phosphorus, vitamin E and antioxidants. Combined with complex carbohydrates like sweet potatoes, this bowl offers sustained energy and satisfying fullness.

Complex carbohydrates digest more slowly than simple carbs and tend to be higher in nutrients and fiber, which can help with weight control and long-term metabolic health. Roasting vegetables brings out natural sweetness and creates pleasant charred edges for texture and depth of flavor.

Makes 4 servings / bowls

Ingredients

1 lb fresh Brussels sprouts, trimmed and halved
1 lb sweet potatoes, peeled and cut into bite-sized pieces
2 large bell peppers, chopped
2 tablespoons avocado oil (or olive oil)
Sea salt and freshly ground black pepper, to taste (about 1/4 teaspoon each)
1 cup quinoa, rinsed
1.5 cups vegetable broth (or water)
1 tablespoon fresh chopped parsley leaves, for garnish

Homemade Tahini Sauce

3 cloves fresh garlic, minced
1/4 cup fresh squeezed lemon juice
1/2 cup tahini (sesame paste)
1/2 teaspoon fine sea salt, or to taste
1/2 teaspoon ground cumin
1/8 teaspoon white pepper (or regular black pepper)
2–4 tablespoons water, or more as needed to thin

Instructions

Preheat your oven to 400°F (about 200°C). Line a large sheet pan with parchment paper for easy cleanup.
Place the halved Brussels sprouts, sweet potato pieces, and chopped bell peppers in a large bowl. Drizzle with avocado oil, season with sea salt and black pepper, and toss until the vegetables are evenly coated.
Spread the vegetables in a single layer on the prepared sheet pan. Roast for 25–30 minutes, flipping once halfway through, until the vegetables are tender and golden with a few charred edges.
While the vegetables roast, rinse the quinoa thoroughly. Cook the quinoa in the vegetable broth according to package directions (typically simmering until the liquid is absorbed and the grains are fluffy).
When the roasted vegetables are ready, fold them gently into the cooked quinoa so everything is evenly combined.
Allow the mixture to cool slightly, then divide it evenly between four meal-prep containers or bowls.
To make the tahini sauce: combine the minced garlic, lemon juice, tahini, sea salt, cumin, and white pepper in a small jar or bowl. Whisk or shake vigorously until smooth. Add water a tablespoon at a time until the sauce reaches your desired consistency.
Drizzle the tahini sauce over each bowl, garnish with chopped parsley, and enjoy. Stored in sealed containers, these bowls will keep in the refrigerator for up to 5 days.

Tips, Variations and Storage

Swap vegetables: swap Brussels sprouts for broccoli, or add cauliflower, carrots, or zucchini based on seasonal availability.
Add extra protein: toss in chickpeas, edamame, or baked tofu for an extra boost.
Spice it up: sprinkle smoked paprika, chili flakes, or curry powder on the veggies before roasting for different flavor profiles.
Storage and reheating: keep bowls chilled in airtight containers for up to 5 days. Reheat in the microwave for 60–90 seconds, stirring halfway, or warm in a skillet until heated through. Add the tahini sauce just before eating for best texture.
Make it dairy-free and vegan by using plant-based broth (already included) and ensuring the tahini is pure sesame paste.

These Roasted Veggie + Quinoa Meal Prep Bowls are an excellent option for busy weeks when you want a nutritious, satisfying meal ready to go. They balance plant protein, complex carbohydrates, and healthy fats while staying flexible to your tastes and pantry staples.

Drizzle, garnish, and enjoy! Sprinkle with chopped fresh parsley before serving.
