Step by step directions
1. Prepare the fajita spice blend - in a small bowl, stir together the spice blend including the onion powder, garlic powder, chili powder, ground cumin, salt, and red pepper flakes.
2. Cook the quinoa - Add half of the spice blend to the cooking liquid with the quinoa for extra flavor. Then, cook the quinoa according to package directions. The rest of the seasoning will be used for the veggies.
Here are three ways you can cook it:
3. Prepare the veggies - Heat your oven to 425°F. In a bowl, toss the vegetables in olive oil and sprinkle with the remaining spice blend. Lay the veggies out on a baking sheet, and bake for 15 minutes. Give them a stir, and return to the oven for another 5 minutes if needed.
4. Portion - divide up the quinoa, veggies, black beans, and additional toppings like salsa or yogurt between four meal prep containers. You can store these portobello fajita meal prep bowls in the fridge for up to 4 days.
5. Serve - serve warm or cold with freshly sliced avocado.
YES! In fact, that sounds like a fantastic idea if you want to keep your oven off! I highly recommend a vegetable grilling plate to stop your veggies from falling between the grates of your grill.
YES! Button or cremini mushrooms work great. I would either half or quarter them and keep an eye on them because they may be done sooner.
Roasted vegetables can become slimy after freeze/thawing, so I don't recommend freezing these meal prep bowls.
- Low carb - swap beans for extra mushrooms or chicken, or swap quinoa for cauliflower rice.
- Meat option - swap mushrooms or add in chicken. My recipe for the juiciest baked chicken breast would work perfectly!
- Quinoa - swap for farro, rice, barley, or cauliflower rice.
- Mushrooms- not a mushroom lover? You might enjoy eggplant, chicken, extra black beans instead.
- Vegetables - alternative vegetables you could try are butternut squash, sweet potato, cauliflower, or broccoli.
- Spice blend - other flavors that would go well in this recipe include: jamaican jerk seasoning, easy greek seasoning blend or even homemade moroccan spice blend in this recipe!
Fridge - store in an air tight container in the fridge for up to 4 days.
Freezer - I would not recommend freezing this portobello fajita meal prep, as I have not had success in freezing roasted peppers, onions or zucchini. These veggies they tend to get slimy after thawing. Instead, you could sub the red pepper, onion and zucchini for veggies that freeze well; such as broccoli or cauliflower.
