Spice Blend

  • 1 teaspoon onion powder
  • 1 teaspoon garlic powder
  • 1 teaspoon chili powder
  • 1 teaspoon ground cumin
  • 1 teaspoon salt
  • 1 teaspoon red pepper flakes

Vegan Portobello Fajita Bowls

  • 3/4 cup quinoa uncooked
  • 2 tablespoons olive oil
  • 4 portobello mushrooms cut into strips
  • 2 bell peppers sliced
  • 1 zucchini sliced
  • 1/2 red onion sliced

After cooking

  • 1 cup black beans
  • lime wedges


  • Heat oven to 425°F. 
  • Stir together the spice blend.
  • Add half of the spice blend to the cooking liquid with the quinoa, then cook quinoa according to package directions. Allow to cool.
  • Toss the vegetables in olive oil and sprinkle with the remaining spice blend. Arrange on one or two baking sheets.
  • Bake veggies for 15 minutes, give them a stir and return to the oven if they are not cooked to your liking. I cooked for 20 minutes total time. Cool.
  • Divide into four meal prep containers: quinoa, veggies, black beans, and additional toppings like salsa or yogurt if desired. We loved ours served with freshly sliced avocado.


Do not add avocado until just before serving.
